Solve this equation Algebraically

x=−1 ,1,−2

Step-by-step explanation:

x3+2x2−x=2

x3+2x2−x−2=2−2

x3+2x2−x−2=0

(x+1)(x−1)(x+2)=0

x+1=0 or x−1=0 or x+2=0

x=−1 or x=1 or x=−2

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

step-by-step explanation:

the answer is 62.8 cubic units
