Answer:
Theres quadrants so -3,9 would be lower about III
6,-6 would be IV
0,-1 1/2 That would be near the 0 obviously so II
To simplify you simply find common variables and add them together to get 56a^3b^3
First add 5 to 16, so -3x=21
then divide by -3, so the answer is
x= -7
I believe the answer is -1
It would be to little because it would only be 30 cents
