Please help ASAP! A model of carry-on luggage has a length that is 5 inches greater than its depth. Airline regulations require that the sum of the length, width, and depth cannot
exceed 57 inches. These conditions, with the assumption that this sum is 57 inches, can be modeled by the function V(x) that gives the luggage's volume, in cubic
inches, in terms of its depth, x, in inches. If its volume is 1500 cubic inches, determine two possibilities for its depth.
Volume = depth length width: 57 - (depth + length)
V(x) = x . (x+5) (57 - (x +x+5))
V(x) = x(x + 5)(52 - 2x)
