3x5 + 4x8 does not have a solution because it is not an equation.
Are you looking for it's derivative? That would be:
15x4 + 32x7
Did you want it's indefinite integral?
∫(3x5 + 4x8) dx = x6/2 + 4x9/9 + C
Or did you actually mean "three times five plus four times eight"? If so, the answer is 47.

A roofing square covers an area of 100 square feet. A standard 4x8 sheet measures 32 square feet (4 feet x 8 feet). To determine how many 4x8 sheets are in a roofing square, divide 100 square feet by 32 square feet, which equals approximately 3.125 sheets. Therefore, you would need about 4 sheets of 4x8 to cover a roofing square, accounting for waste and cuts.
That depends - whether your 4x8 bricks are in centimetres, metres, inches or feet.

There are a few things. If you can get 4x8 Hardibacker, that would be best. 3x5 Hardibacker would be second-best, just because of the extra seams you'll have to put in it. Mold-resistant drywall would work if that's all you can get.

For a single term, the "degree" refers to the power. The coefficient is the number in front of (to the left of) the x.
