The answer would be 132 because the formula for find circumference while using radius is 2(3.14)r .

C= 2(3.13)21

C= 6.28 • 21 = 131.88

131.88 rounded is 132

Step-by-step explanation:

Given

6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9

Sum the 2 expressions by adding like terms, that is

Which expression is equivalent to 2x^2+2x-4/2x^2-4x+2
lord [1]
You need to factor the numerator and denominator...

(2x^2+4x-2x-4)/(2x^2-2x-2x+2)

(2x(x+2)-2(x+2))/(2x(x-1)-2(x-1))

((2x-2)(x+2))/((2x-2)(x-1))  so the (2x-2)s cancel out leaving

(x+2)/(x-1)
