Which of the following equations are true? Select three that apply. A
(2x−1)(x2+4x+3)=2x3+7x2+2x−3

B
(4x2−3x+6)+(5x2−8)=9x2−3x−2

C
(8x−4x2)+(2x2−5x)=−2x4+3x

D
(4x2+4x−5)−(6x2−5x−3)=−2x2−x−8

E
(3x3−5+2x)−(5x−6+x3)=2x3−3x+1

ANSWER: A, B, E :)

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:
