Ok so from experience on this site
3x2=3x^2
people don't know how to put exponents
3x^2-y^3-y^3-z
simplify first
3x^2-2y^3-z
x=3
y=-2
z=-5
3(3^2)-2(-2)^3-(-5)
3(9)-2(-8)+5
27+16+5
48

<span> Suppose the # of litres in the small container is 'x'.
This would make '2x' litres of water in the larger container.
After taking 8 litres from both containers, the following equation can be written:
(2x-8) = 3 (x-8)
Open the brackets:
2x-8 = 3x-24
Collect like terms:
x = 16
There were 16 litres in the smaller container</span>
Triangle area = 6 * 8 / 2 = 24 square inches
Prism Surface Area = 2 * triangle area + height * (side a + side b + side c)
228 = 2 * 24 + height * (6 + 8 + 10)
228 -48 = height * 24
height = 180 / 24
height = 7.5
