Solve the problem.The following table gives data on two different solar modules being developed for use in roofing.
You must determine the size of the frame needed to support each panel on a roof. (Note: The sides of each frame will form a right triangle, and the hypotenuse of the triangle will be the width of the panel.) Use the Pythagorean theorem to find the dimensions of the legs for each frame if one leg is twice the length of the other. Round your answers to the nearest tenth when necessary.

Solve the problem.From a 36-inch by 36-inch piece of metal, squares are cut out of the four corners so that the sides can then be folded up to make a box. Let x represent the length of the sides of the squares, in inches, that are cut out. Express the volume of the box as a function of x.
A. V(x) = 4x3 - 144x2 B. V(x) = 4x3 - 144x2 + 1,296x C. V(x) = 2x3 - 108x2 D. V(x) = 2x3 - 108x2 + 36x
