Look at the numbers below. −9.8 −5.4 1.0 14.8 which shows the best way to add these numbers using the commutative and associative properties? a. (–9.8 + 1.0) + (–5.4 + 14.8) b. (–9.8 + 14.8) + (–5.4 + 1.0) c. (1.0 + 14.8) + (–9.8 + (–5.4)) d. (1.0 + (–9.8)) + (14.8 + (–5.4))

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
