Answer:
Option C. 
Step-by-step explanation:
we know that
The volume of the triangular prism is equal to

where
B is the area of the triangular base
H is the height of the prism
Convert 9 ft to yd
Remember that
1 ft=1/3 yd
9 ft=9*(1/3)=3 yd
<em>Find the area of the base B</em>

we have

substitute the values in the formula


1/3x + 2 = 4/3x - 5
2 + 5 = 4/3x - 1/3x
7 = x
y = 1/3(7) + 2
y = 7/3 + 2
y = 7/3 + 6/3
y = 13/3
solution is : (7,13/3) <=
6[5x(41-36) - (8+14)]
6[5x(5) - 22]
6[25x - 22]
150x - 132
