Factor completely 2x^2 + 9x + 4. a. (2x + 2)(x + 2) b. (2x + 1)(x + 4) c. (2x + 4)(x + 1) d. (2x + 2)(x + 4)

2x^2 + 9x + 4 = (2x + 1)(x + 4)

because

(2x + 1)(x + 4)

= 2x^2 + x + 8x + 4

= 2x^2 + 9x + 4

Answer is B. (2x + 1)(x + 4)

Hope it helps

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:

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3
