What is an equivalent expression example?
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.

How do you know if equations are equivalent?
To solve this, you need to find “x” for each equation. If “x” is the same for both equations, then they are equivalent. If “x” is different (i.e., the equations have different roots), then the equations are not equivalent.
What is this expression equivalent to A -> B?
Hence, a. (a+b) is equivalent to a2+ab.
Which equation is equivalent to log2n 4?
The correct answer is B) 16.

And 3x plus 6 is not equal to 2x + 6 thereby eliminating choice C as well.
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.

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.
Algebraic expressions, such as
4 x + 3 y − 2 w 2,
4x+3y-2w^2, 4x +3y−2w2, contain variables, numbers, and mathematical operations. Algebraic expressions may be written in different ways, but still mean the same thing.
Identifying Equivalent Expressions
We can use properties of arithmetic and the combining of like terms to write equivalent expressions.

What is an Algebraic Expression?
An algebraic expression is an expression which consists of variables, coefficients, constants, and mathematical operators such as addition, subtraction, multiplication and division. Generally, if two things are the same, then it is called equivalent. Similarly, in mathematics, the equivalent expressions are the expressions that are the same, even though the expression looks different. But if the values are plugged in the expression, both the expressions give the same result.
What is the equivalent fraction of 2/3?
For example, if we multiply the numerator and denominator of 2/3 by 4 we get. 2/3 = 2×4 / 3×4 = 8/12 which is an equivalent fraction of 2/3.
