Answer:
it should be 8 and 5, the first one
Write x-4 instead of y.
x²+(x-4)²=40
x²+x²-8x+16=40
2x²-8x-24=0
x²-4x-12=0
(x-6)(x+2)=0
x=6 or x=-2
for x=6, y=6-4 = 2
for x=-2, y=-2-4 = -6
1. 5/y=2/3x +3
2. y= 7/1-4
3. y=2/5x8
4. y=-3/4 +1 I could be wrong but I think this is right
The volume of the triangular prism is the Area of the base times the height
the area of the base is:

and the volume is:

now b=10 yards, a=20 yards, and V=600 yards^3
we clean the height

the answer is height = 6 yards
