Step-by-step explanation:
X

38 -> 24x
x > 38 -> 31(x-38) + 912
912 = 24*38 (You will have to have 38 hours to be able to be in this part of the piece wise function)
Answer:7feet
Step-by-step explanation:
perimeter(p)=54ft
Width(w) +13=Length(L)
Perimeter=2xLength+2xwidth
P=2xL+2xw
L=w+13
54=2(w+13)+2w
54=2w+26+2w
Collect like terms
54-26=2w+2w
28=4w
Divide both sides by 4
28/4=4w/4
7=w
Width =7feet
