Can someone me? ? and tell me how you got your answer? ? i keep getting -6a^2b^2

You're getting the answer that any regular person who didn't see the exponents floating way above the expressions there would get.

I think the problem is actually:

Choice D

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
