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.
