  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-(8×8) = 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.
