Answer:

(x - 5) and (x + 1)

Step-by-step explanation:

x² - 4x - 5

consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)

the factors are - 5 and + 1 , since

- 5 × + 1 = - 5 and - 5 + 1 = - 4 , then

x² - 4x - 5 = (x - 5)(x + 1)

Let's call the first unknown integer x and the second one y.

"Four times an unknown integer"

We can write it as 4x

"Multiplied by three times the unknown integer plus a different unknown integer"

4x is multiplied by 3x+y, so 4x(3x+y)=12x²+4xy

"Equals 100."

12x²+4xy=100

And so the answer is C: 12x²+4xy-100=0

Find the value of x.

hichkok12 [17]

<h3>Angles sum up to:</h3><h3>( n - 2 ) × 180 = ( 5 - 2 ) × 180 = 3 × 180 = 540</h3>

$x + 4x + 4x + 135 + 135 = 540$

$9x + 270 = 540$

$9x = 540 - 270 \\ 9x = 270$

$x = \frac{270}{9} = 30$
