# Using distributive property to write an equivalent expression

We can use this distributive property to write equivalent algebraic expressions. Distributive Property. Multiplying a number by a sum or difference is the same as multiplying by each number in the sum or difference and then adding or subtracting. Examples : 6(2 + 4) = 6(2) + 6(4) 8(5 – 3) = 8(5) – 8(3) Writing Equivalent Expressions Using Distributive Property – Examples. Example 1 :

So we’re going to multiply 7 times 3 is 21 and this Y is going to come along for the ride. So theMoreSo we’re going to multiply 7 times 3 is 21 and this Y is going to come along for the ride. So the equivalent expression that we generated in this case by using a distributive property is 49 plus 21y.

## 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 to write equivalent expression?

equivalentleft (x+x,3xright) equivalent(x+x,3x) 2. Apply the formula: e q u i v a l e n t ( a, b) mathrm {equivalent}left (a,bright) equivalent(a,b) =false, where. a = x + x. a=x+x a= x+x and. b = 3 x. b=3x b =3x.

## 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.

## What is an equal expression?

What is an equal expression? If two things are equivalent, they are the same. Equivalent expressions are expressions that are the same, even though they may look a little different. If you plug in the same variable value into equivalent expressions, they will each give you the same value when you simplify.

## 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 does it mean to write an equivalent expression?

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 are 2 examples of distributive property?

It is used to solve expressions easily by distributing a number to the numbers given in brackets. For example, if we apply the distributive property of multiplication to solve the expression: 4(2 + 4), we would solve it in the following way: 4(2 + 4) = (4 × 2) + (4 × 4) = 8 + 16 = 24.

## How do you make an equivalent expression with exponents?

The product of powers property says that when we multiply powers with the same base, we just have to add the exponents. So, xaxb = x(a + b). As you can see, we keep the base the same and add the exponents together.

## 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.

## 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.
