6x^2 + 37x - 60 = 6x^2 - 8x + 45x - 60 = 2x(3x - 4) + 15(3x - 4) = (3x - 4)(2x + 15)

For this case we have the following polynomial:

6x ^ 2 + 37x - 60

Rewriting the polynomial in the term of degree 1 we have:

6x ^ 2 + 37x - 60 = 6x ^ 2 - 8x + 45x - 60

Then, we group the expression obtained as:

(6x ^ 2 - 8x) + (45x - 60)

In the first parenthesis we do 2x common factor.

In the second parenthesis we make a common factor 15.

We have then:

2x (3x - 4) + 15 (3x - 4)

Then, we make a common factor of both parentheses:

(3x - 4) (2x + 15)

Answer:

The expressions that represent integer factors of 6x ^ 2 + 37x - 60 for all values of x are:

(3x - 4) (2x + 15)

What is the measure of the smallest interior angle of the hexagon shown?
yan [13]
<h3>Answer:  C) 70 degrees</h3>

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

Explanation:

We have n = 6 sides, so the interior angles must add to 180(n-2) = 180(6-2) = 720 degrees

Lets add up the angles, set the sum equal to 720 and solve for x

x+2x+115+2x+115+2x = 720

7x+230 = 720

7x = 720-230

7x = 490

x = 490/7

x = 70

This makes angle 2x = 2*70 = 140 degrees

We see that x = 70 is the smallest angle, so that's why C is the answer.

How do you rewrite this problem in slope-intercept form
Sergio039 [100]

Solution

-6x - 3y = 9              Add 6x to both sides

-6x + 6x - 3y = 9 + 6x

-3y = 9 + 6x             Or more conventionally

-3y = 6x + 9             Divide by - 3

y = 6x/-3 + 9/-3

y = - 2x - 3
