Answer:

$\huge\boxed{Option \ 3 : (fg)(x) = 9x^3+27x^2}$

Step-by-step explanation:

$f(x) = 3x+9\\g(x) = 3x^2$

Multiplying both

$(fg)(x) = (3x+9)(3x^2)\\(fg)(x) = 9x^3+27x^2$

Answer:

9x³ + 27x²

Step-by-step explanation:

What the question is asking is to multiply f(x) and g(x) together:

Step 1: Write out expression

(fg)(x) = 3x²(3x + 9)

Step 2: Distribute

(fg)(x) = 9x³ + 27x²

Please help me with this homework

The answer is 1.25.

The equation for slope is rise over run. Y is the rise and X is the run. The point equation is (y2-y1)/(x2-x-1) = slope.

Plugging in the numbers: (-4-1)/(-4-0) = 1.25

1. 5x + 2(x +6) simplify each expression

irina [24]

1. 5x+ 2(x+6)
= 5x+ 2x+ 2*6 (distributive property)
= 5x+ 2x+ 12
= (5x+ 2x)+ 12 (combine like terms)
= 7x+ 12

The correct answer is C. 7x+12~

2. <span> -3m + 3(m + 6)
= -3m+ 3m+ 3*6
= -3m+ 3m+ 18
= (-3m+ 3m)+ 18
= 18

The correct answer is D. 18~</span>
