How To Write An Equivalent Expression? Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order usually x-term before constants.
How do you identify equivalent expressions?
Equivalent Expressions Equivalent Expressions are expressions that have the same value. They may look different but will have the same result if calculated. For example, and are equivalent expressions. See why below: The two expressions have the same answer, 27. Therefore, we can say that they are equivalent expressions.
How do you find the equivalent expression?
equivalent expressionshave the same value but are presented in a differentformat using the properties of numbers eg, ax + bx = (a + b)x are equivalent expressions. Strictly, they are not “equal”, hence we should use 3 parallel lines in the”equal” rather than 2 as shown here.
How to solve equivalent expressions?
Equivalent equations are algebraic equations that have identical solutions or roots. Adding or subtracting the same number or expression to both sides of an equation produces an equivalent equation. Multiplying or dividing both sides of an equation by the same non-zero number produces an equivalent equation.
What is the meaning of equivalent expressions?
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable. To check whether a more complex expression is equivalent to a simpler expression:
How do you write an expression equivalent?
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
What is an example of an equivalent expression?
Examples of Equivalent Expressions 3(x + 2) and 3x + 6 are equivalent expressions because the value of both the expressions remains the same for any value of x. 3x + 6 = 3 × 4 + 6 = 18. and can also be written as 6(x2 + 2y + 1) = 6×2 + 12y + 6. In this lesson, we learn to identify equivalent expressions.
What is equivalent number expression?
An equivalent expression is an expression that has the same value or worth as another expression, but does not look the same. An algebraic example of equivalent expressions is: 2(2x – 3y + 6) is equivalent to 4x -6y + 12.

So in this example you have a on the outside you can’t add B and CMoreBasically you distribute. So in this example you have a on the outside you can’t add B and C together. So you distribute that a. So this becomes a times B which is equal to a B. And then a times C.
What is this expression equivalent to A -> B?
Hence, a. (a+b) is equivalent to a2+ab.
What expression is equivalent to 81?
Some expressions that are equivalent to 81 are 9^2, 3\times3^3, and 8^2+17.
Why do we use equivalent expressions?
Equivalent expressions are expressions that have the same value. Writing equivalent expressions can make them easier to work with and solve. For example, these two expressions are equivalent.
Are the two expressions equivalent?
Two expressions are equivalent if they can be simplified to the same third expression or if one of the expressions can be written like the other. In addition, you can also determine if two expressions are equivalent when values are substituted in for the variable and both arrive at the same answer.
What is an example of a equivalent fraction?
Equivalent fractions are fractions that represent the same value, even though they look different. For example, if you have a cake, cut it into two equal pieces, and eat one of them, you will have eaten half the cake.

Which equation is equivalent to log2n 4?
The correct answer is B) 16.
Which expression is equivalent to sine of 7pi 6 )?
The value of sin 7pi/6 in decimal is -0.5. Sin 7pi/6 can also be expressed using the equivalent of the given angle (7pi/6) in degrees (210°). Since the sine function is a periodic function, we can represent sin 7pi/6 as, sin 7pi/6 = sin(7pi/6 + n × 2pi), n ∈ Z.

Why do we use equivalent expressions?
Equivalent expressions are expressions that have the same value. Writing equivalent expressions can make them easier to work with and solve. For example, these two expressions are equivalent.
What is equivalent expression?
As the name suggests, equivalent expressions are algebraic expressions that, although they look different, turn out to really be the same. And since they’re the same, they will yield the same results no matter what numbers we substitute for their variables. Let’s consider this algebraic expression: 2 ( x ^2 + x ).
What is an algebraic expression?
An algebraic expression is a string of numbers, variables, mathematical operations, and possibly exponents. For example, 4 x + 3 is a basic algebraic expression. Or we could get a little more complex with 3 x (2 x ^2 + 2 x – 5) + 6 y. Notice that both of these examples contain the previously listed elements of an algebraic expression: numbers, variables, and mathematical operations, and the second expression contains the optional exponent.
Why are graphs exactly the same?
Well, since equivalent expressions produce identical solutions for all values, their graphs are exactly the same . If we wanted to, we could graph a hundred equivalent expressions, and the result would still be one line because all the expressions would produce the same solutions.
Why do two expressions have their own tracks?
In fact, if we graph the two expressions, we can see that they only intersect at that one point where they happen to yield identical solutions. However, they have their own tracks before and after that point because they’re not equivalent expressions. While we’re at it, let’s see what happens when we graph the following equivalent expressions:
What happens when you plug in matching values of the variables into two mathematical expressions?
If we plug in matching values of the variables into two mathematical expressions, and we get a different value out from each expression, then the two expressions are not equivalent.
What happens if you use the same number for x?
Because these two expressions are really the same, no matter what number we substitute for x, the results will always be identical. If we use 0, both expressions come out to 0. If we use 10, both expressions come out to 220. If we use 100, both expressions come out to 20,200. We get the same result no matter how large or small the number we use for x.
How to tell if an equation is a true number sentence?
An equation has one specific solution or set of solutions that will make the number sentence true. In this case, the equation is a true number sentence when x = 1. There is one specific solution. In an expression, however, since there’s no equal sign, variables are free to be variables.
What are equivalent expressions?
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value (s) for the variable (s).
When two expressions are equivalent, what is the meaning of the expression?
If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable. Arrange the terms in the same order, usually -term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
How to make an equation true for all values of a variable?
For the equation to be true for all values of the variable, the two expressions on each side of the equation must be equivalent. For example, if for all values of , then: must equal . must equal . Distribute any coefficients on each side of the equation.
How to distribute coefficients?
Distribute any coefficients: Combine any like terms on each side of the equation: -terms with -terms and constants with constants. Arrange the terms in the same order, usually -term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
What happens if all the terms in two expressions are identical?
If all of the terms in the two expressions are identical, then the two expressions are equivalent.
How do we rearrange formulas?
Formulas are equations that contain or more variables; they describe relationships and help us solve problems in geometry, physics , etc.
