Answer:
B
Step-by-step explanation:
Lets start with finding the volume of the pool
The formula for the volume of a rectangular prism is
V=l*w*h where l=length w=width and h=height
plug in the data we know
V=40*20*4
V=3200ft³
Now for the hot tub.
3200ft³*1/4=800ft³
Add the volumes together
3200+800=4000ft³
Answer=4000ft³

Answer:
9 = n
Step-by-step explanation:
12 = 6(n – 7)
Divide by 6 on both sides
12/6 = 6/6(n – 7)
2 = n-7
Add 7 to each side
2+7 = n-7+7
9 = n
