Given −7 is one of the roots of the quadratic equation (x + k)2 = 16, where k is a constant, find the values of k.

Taking square root on the both sides of equation (x + k)² = 16 we get,

Making two conditions for ± 4 i.e

1) x + k = 4

2) x + k = -4

the figures below are made out of circles, semicircles, quarter … 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). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
