Answer:
4
Step-by-step explanation:
The perimeter of each square window is 4 times the length of one side, so is 20 feet.
80 feet can be divided into 80/20 = 4 sections of 20 feet each.
Shelly has enough lights to surround 4 windows.
5) w/8 =11+5 → w/8=16
w=16÷8=2
6)a/-2 -6=1
a/-2=7
a=7×-2=-14
7)k/2=22
k=44

−3(n+3)−10(8n+9)
(−3)(n)+(−3)(3)+(−10)(8n)+(−10)(9)
=−3n+−9+−80n+−90
=−3n+−9+−80n+−90
=(−3n+−80n)+(−9+−90)
=−83n+−99 <- ANSWER
