-24

Step-by-step explanation:

f(3)=-2

g(-1)=6

Okay so to find out how to locate these answers, you plug in the x-value as the number inside, so for f(3), you're trying to find out what the y-value is at x=3 which would be -2.

Then, with these values, you can just solve using PEMDAS.

-6*f(3)-6*g(-1)=_

-6*-2-6*6_

12-36=-24

I think that the answers would be

bc : 17.5

ab : 20.1

C : 90 °

A : 60 °

B : 30 °

perimeter : 47.6

area : 87.5
