Question

Select all expressions equivalent to 8x - 24.
2(2x - 12)
4(2x - 4)
8(x - 3)
2(4x - 12)

Answer 1

Answer:

8(x-3)

2(4x-24)

Step-by-step explanation:

You are using the distributive property. Multiply the number outside of the parentheses by each number within the parentheses.

In 8(x-3) = 8x - (8×3) = 8x-24

In 2(4x-12) = (2 × 4x) - (2 × 12) = 8x-24

Answer 2

8(x-3) and 2(4x-12).
