50 points multiply the polynomials. (x + 3)(3x^2 + 8x + 9) a. 3x^3 + 17x^2 + 33x - 27 b. 3x^3 + 17x^2 + 33x + 27 c. 3x^3 + 17x^2 - 15x + 27 d. 3x^3 + x^2 + 33x + 27

B) 3x³ + 17x² + 33x + 27.

Step-by-step explanation:

Given  : (x + 3)(3x² + 8x + 9).

To find : Multiply the polynomials.

Solution : We have given that :

(x + 3)(3x² + 8x + 9).

Distribute x over (3x² + 8x + 9) and 3 over (3x² + 8x + 9).

x (3x² + 8x + 9) + 3 (3x² + 8x + 9).

3x³ + 8x² + 9x + 9x² + 24x + 27.

Combine like terms

3x³ + 8x² + 9x² + 9x + 24x + 27.

3x³ + 17x² + 33x + 27.

Therefore, B) 3x³ + 17x² + 33x + 27.

1/4 because there is 4 grades.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
