It would be 2u3+4u2-2u-4u2-8u+4= 2u3-10u+4
Answer:
A. pi(6)^2* 8
Step-by-step explanation:
First we expand the brackets:
-2a + 8 + 6a = 36
4a + 8 = 36
We then need to get the a's onto one side and the numbers onto the other:
4a = 28
We can then divide to get an x by itself:
a = 28/4 = 7
The third one is the smallest
Answer: 0
Step-by-step explanation: 18a + 3 = 3
-3 -3
--------------
18a = 0 you can't divide 18 and zero it would be 0
