Question

3x(x+8)=180 i dont know what to do

Answer 1

First, you would remove the parenthesis.
Then, you would combine like terms. So 3x+x is 4x. Next, you would subtract the 8 from both sides. 8-8 gets crossed out. And 180-8 is 172. After that you haves 4x=172. You would just divide the 4 from the 172 and get 43.
Answer: X=43
