Use the substitution method to solve the system of equations. Choose the correct ordered pair. 2x + 4y = 14 x = 3
Anna71 [15]
Because we have x = 3, we can substitute it. But first, let's convert 2x + 4y = 14 into y-slope intercept form.

2x + 4y = 14
Subtract 2x from both sides.
4y = -2x + 14
Divide both sides by 4.
y = -1/2x + 3.5

Now substitute.

y = -1/2(3) + 3.5
y = -1.5 + 3.5
y = 2

Find the surface area of this cube. Be sure to include the correct unit in your answer.
NikAS [45]
Are the dimensions 8yd x 8yd x 8yd? If so this is how you do:

First calculate the area or one side. Then multiply it by 6 as all the sides of the cube have the same area.

Side area = 8yd x 8yd = 64yd^2

Surface area = 6 x 64yd^2 = 384yd^2
