jawhuss
A. 6x + 12 + 6x - 8
6x + 6x + 12 - 8
12x + 4

B. 3(2*5 + 4) + 2(3*5 - 4)
3(10 + 4) + 2(15 - 4)
30 + 12 + 30 - 8
= 64

C. For the first one (part A) I distributed 3 and 2 to everything that was in the parentheses. Then I got 12x + 4 because you cant add them cause they don’t have like terms. For the second question (part B) I simply just replaced x with 5 and I solved the rest of the problem which got me to x = 64.

Hope this helps!
