Question

Which of the following uses the distributive property correctly?

9(m – 2) = 9(m) – 9(2)
9(m – 2) = 9(m) – 2
9(m – 2) = 9 – 9(2)
9(m – 2) = 9(m) + 9(2)

Answer 1

9(m – 2) = 9(m) – 9(2)

Explanation:

The distributive property:

a(b - c) = ab - ac

`\Downarrow`

9(m - 2) = (9)(m) - (9)(2)

Answer 2

Answer: A

You’re basically adding m - 2 nine times
So it’s 9m - 18
Or 9m - 9(2)
