What you want to do is find the volume of the first prism and divide the volume by 1.5 to get the surface area. then divide be 4 since it is a square base.
Answer:
None of the first 4 do. so I guess the answers E.
Step-by-step explanation:
The answer is x= 4 and y= -3
6x-4y=36 -- (1)
2x-8y=32- (2)
from (1)
-4y= 36-6x
y= -9+3/2x
(3) into (2)
2x-8(-9+3/2x)=32
2x+72-12x=32
72-10x=32
-10x= -40
x= 4
sub x=4 into y= -9+3/2x
y= -9+3/2(4)
y= -3
