Answer:
see below
Step-by-step explanation:
Using the segment addition postulate
AB + BC = AC
x+2 + 7x-3 = AC
Combine like terms
8x -1 = AC
Using the segment addition postulate
PQ + QR = PR
8y+5 + QR = 13y+25
Subtract 8y from each side
5 + QR = 13y-8y+25
5 + QR = 5y+25
Subtract 5 from each side
QR = 5y+25-5
QR = 5y+20
The rate of change or slope is 6 inches or half a foot per year. The initial value, or y intercept is 7 ft. Plug this into mx+b form to get y=.5x+7

Answer:
3x
___
2
Step-by-step explanation:
we know that
high of the water=14 in-2 in=12 in
wide=39.75 in
deep=11.375 in
so
volume of the water in the tank=39.75*11.375*(12)-----> 5,425.875 in³
the answer is
5,425.875 in³ of water
