A rectangular prism has 6 surface.
Answer:
3x+4y-12=0
y intercept = -constant term/coefficient. of y
= 12/4
=3
There are going to be two solutions because the "biggest" x is x^2 but you can factor to find what they actually are.
3x + 4(2) = 20
3x + 8 = 20
3x = 12
x = 4
(4,2)
You have y=2 then all you need to do is plug 2 into the y in the equation 3x + 4y = 20 and do the math to find x. Hope this helps
