xoxo-Just replace a with 3 and b with 2.so the answer is 15.......

I really got confused on how to do this...Can you guys tell me the answer then show me how you got it? Thanks a lot! xoxo

Just replace a with 3 and b with 2.

4*(3) - (2)*2 + 7

= 15

4a-b^2+7
4(3)-2^2+7
12-4+7
so the answer is 15.

4a - b^2 + 7
4*3 - 2^2 + 7 =
12 - 4 + 7 = 15
