Step-by-step explanation:

f(x)=x²-2x+3

f(x)=-2x+12

x²-2x+3=-2x+12

x²-9=0

(x-3)(x+3)=0

x=3,-3

when x=3 ,f(x)=-2×3+12=-6+12=6

when x=-3,f(x)=-2×-3+12=6+12=18

solutions are (3,6);(-3,18)

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
