Answer:

A. -8(f + g)

Explanation:

First, let us simplify -15f - f + 10g -2g + 8f

Given: -15f - f + 10g -2g + 8f

Combine like terms: -8f + 8g

Now that we have it simplified, we can tell that our answer will not be B or C.

I can tell you that the answer to this question is A because -8 times g is -8g and we need it to be positive.
