Step-by-step explanation:
the perimeter of a rectangle is
2×length + 2×width =
2×(x + 10y) + 2×(7x² - x + 9y) =
2x + 20y + 14x² - 2x + 18y =
14x² + 38y
1/2(x+6)=2x
1/2x + 3 = 2x
x + 6 = 4x
3x = 6
x = 2
5-2x+7x-h
5-2(2)+7(2) = h
h = 5 - 4 + 14
h = 1 + 14
h = 15

Answer:
total volumA.4ft³ is your answere
h=d=1.5ft
r=1.5/2=0.75ft
total volume=volume of (cylinder + hemisphere)
=πr²h+2/3πr³=πr²(h+2/3r)=22/7×0.75²(1.5+2/3 ×0.75)=3.53=4ft³
