The formula for the surface area of a cube is: SA= 6((length of side)^2).
So if the surface area is 96, first divide by 6. And you get 16. Next you find the square-root of 16 and get 4. So the length of each side is 4 inches.
The formula for volume of a cube is V=(length of side)^3.
So 4 raised to the third power is: 4*4*4.
The volume of the cube is 64 inches cubed.

Answer:
x = 20
Length = 20ft
Width = 12ft
Step-by-step explanation:
A = 240
x^2 - 8x = 240
x^2 - 8x - 240 = 0
x^2 - 20x + 12x - 240 = 0
x(x-20) + 12(x-20) = 0
(x+12)(x-20) = 0
x = 20
x = -12 (which we discard since x is a length)
So the dimensions are 20ft and 20-8 = 12ft
Answer:
2y + 2x = 0
Step-by-step explanation:
First you have to find the slope of the line.
Parallel lines have same slope
2y = -2-2x
y=-1-1x, y=-1x-1
slope = -1
Use point slope formula
y-y=m(x-x)
y-(-9) = -1(x-9)
y+9 = -1(x-9)
y+9 = -1x+9
y = -x
y + x = 0
2y + 2x = 0
