Plug the -4 into equation

f(-4) = 5(-4) -3

multiply 5•-4= -20

then subtract -20-3

when you have two negatives you add

= -23
f ( - 4) = 5( - 4) - 3 =  - 23

A fence completely surrounds a pool,that is 30 feet by 10 feet.what is the approximate length,in feet,of the fence
tamaranim1 [39]
Because the fence's dimensions is 30 feet by 10 feet, you can assume that one side of the pool is 30 feet while the other, non-congruent side, is 10 feet. The formula for perimeter, which you are trying to find,  is 2L+2W=P. In this problem, 30 will be your L and 10 will be your W. Therefore, 2(30) +2(10)=80.

So 80 feet will be your answer.
