Answer:

Option C. (3x + 2)(3x - 1) is the answer.

Step-by-step explanation:

The given expression is 9x² + 3x - 2 and we have to factorize the expression given.

9x² + 3x - 2 = 9x² + 6x - 3x - 2

= 3x(3x + 2) - 1(3x + 2)

= (3x + 2)(3x - 1)

So the factorized form of the expression is (3x + 2)(3x - 1).

Option C is the correct answer.

Answer:

Choice C is the answer.

Step-by-step explanation:

We have given an expression.

9x²+3x-2

We have to factorize given expression.

Split the middle term of above expression so that the sum of two terms should be 3 and their product be -18.

9x²+6x-3x-2

Making groups and taking common , we have

3x(3x+2)-1(3x+2)

Taking 3x+2 as common, we have

(3x+2)(3x-1) which is the answer.

Find the measure of x.

Ratling [72]

<h3>Answer: B. x = 6</h3>

==========================================================

Explanation:

Since the vertical lines are parallel, this means the alternate exterior angles shown are congruent.

Set them equal to each other and solve for x.

15(x+2) = 120

15x+30 = 120

15x = 120-30

15x = 90

x = 90/15

x = 6

Or we could have the steps like this

15(x+2) = 120

x+2 = 120/15

x+2 = 8

x = 8-2

x = 6

Verizon [17]

ANSWER

Frequency=2

Midline =3

Amplitude =5

Period =π

EXPLANATION

We have:

$f(x) = 5 \cos(x) + 3$

The given function is of the form;

$f(x) = a\cos(bx) + c$

where

a=|5| =5 is the amplitude

and b=2 is the frequency.

and 2π/b=2π/2=π

The range of the given function is

8≤y≤-2

The midline is

$\frac{8 + - 2}{2} = \frac{6}{2} = 3$
