4. Consider the equation x2 + 1 = 7 - X.

A. Verify that this has the solution set {-3,2).​

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).

Find the area of the triangle formed by the origin and the points of intersection of parabolas y=−3x^2+20 and y=x^2−16.

What are the values of each variable in the diagram below?
