Answer:
C
Step-by-step explanation:
Hey, okay, so you just FOIL it.
F - first, O - outside, I - inside, L - last.
multiply x&2x, x&3y, -3y&2x, -3y&3y.
So it should look like this:
2x^2+3xy-6xy-9y
so the final answer should be
2x^2+3xy-9y
Answer: 9
explanation:
4+(-7)= -3
next, you multiply -3 and -3 which is 9 as the two negatives cancel out
Subtract 6 on both sides


Multiply -2 on both sides to get "x" by itself

x = -8
