A polynomial of degree 4 has a zero of multiplicity 2 at x=4 and zeros/roots of multiplicity 1 at x = 0 and x = -2. This polynomial goes through the point (3,-75). Find the formula for the polynomial P(x).

The figures below are made out of circles, semicircles, quarter circles, and a square. find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations).
