Question

Which expression is NOT equivalent to? :

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

A. -8(f + g)
B. 8g - 8f
C. -8f + 8g
D. 8(g-f)

Answer 1

A, I’m pretty sure it’s A

Answer 2

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.
