What is simplify this expression: 13 (-12) - (-5) =
a. -30
b. 6
c. 30
d.-6?

So its 13 multiply by -12 which is -156 okay. Then you have a - (-5) which is positive 5 which will get you total answer of -151. I don't see any of those answers to be honest in your answer list; but you might get my point of how to do it.

Number 5 is 50 degreesnumber 6 is 45 degreesnumber 7 is 60 degreesnumber 8 is 45 degrees

The correct answer is d, hope this
