Question

What is the equivalent expression that represents its perimeter 80x-64 HELP!


1)80x-64

2) 8x

3) 10x-8

4)8(10x-8)

Answer 1

Answer:

4. 8(10x-8)

Step-by-step explanation:

An "equivalent expression" has the same value to that of the original expression.

• 8(10x-8) is an equivalent expression of 80x-64 because both have the same value.

Let's solve.

8(10x-8) = 80x-64

8x10x-(8x8) = 80x-64

80x-64 = 80x-64

This makes the answer correct.

• Choice 1 is just the same expression, so it's not an equivalent expression.
• Choice 2 and 3 are not equivalent expressions as well.
