Step-by-step explanation:

A rectangular prism has a length of 8 inches and a width of 6 inches. The lateral area is 84 square inches. What is the height of the prism?

Find the perimeter of the base.

P=2l + 2wPerimeter of a rectangle

P=2(8) + 2(6)Substitute: l = 8 and w = 6

P=28

Use the formula for lateral area.

L=Ph

84=(28)hSubstitute: L = 84 and P = 28

h=3Solve for h.

The height of the prism is 3 inches.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
