2x – 2y =6
4x+4y=28
4x - 4y = 12
4x+4y = 28
8x = 40
4x+4y = 28
8x = 40
which solution can be used to fill in both blanks in the table?

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
