Answer 7

your welcome itry to be the best

Answer 8

How did you get -128 for the first one? I got -52. Could you explain? Thanks!

Answer 9

I meant can you post the math as to how you arrived at your answer? Here's how I got -52, maybe you can show me where I went wrong.

6 * (-2) * 3 = -36

+

2 * (-2) * 2 = -8

+

4 * (-2) = -8

-36 + -8 + -8 = -52

Thanks

Answer 10

we both are wrong miss calculations

Answer 11

I think you left out a 2 here: (-2)2+4(-2) as it is 2* the Variable X * 2, not 2 x 2?
