Question

5x + 2(x + 6) (1 point) Responses 7x + 6 7 x + 6 7x2 + 12 7 x 2 + 12 7x + 12 7 x + 12 7x (x + 6)

–3m + 3(m + 6) (1 point) Responses 6 6 –6m + 6 –6 m + 6 6m + 18 6 m + 18 18

Answer 1

To simplify the first expression, you need to distribute 2 to both terms inside the parentheses:

5x + 2(x + 6)
= 5x + 2x + 12
= 7x + 12

So the simplified form is 7x + 12.

For the second expression, you also need to distribute -3 to both terms inside the parentheses:

-3m + 3(m + 6)
= -3m + 3m + 18
= 18

So the simplified form is 18.
