x^3 - 3x^2 - 18x
Using the FOIL method, I arrived at my solution!
What is the complete question and what are the choices??
There is no picture given but I’m assuming you need to simplify it. The answer is 9x + 12
7(2x+5)=4x-9-x
14x+35=3x-9
11x = -44
x = -4
7(2*-4+5)=4*-4-9--4
7(-3)=-21
-21=-21. so it checks out and x = -4
