Answer:

B.   (x - 6)(x + 2).

Step-by-step explanation:

x^2 - 4x - 12

We need 2 numbers whose product is the last number -12 and whose sum is the coefficient of x (-4).

These numbers are -6 and + 2.

So the factors are (x - 6)(x + 2).

Doss [256]

Answer:

y=-1/7x + 12/7

Step-by-step explanation:

Start by finding the slope

m=(1-0)/(-5-2)

m=-1/7

next plug the slope and the point (-5,1) into point slope formula

y-y1=m(x-x1)

y1=1

x1= -5

m=-1/7

y- 1 = -1/7(x - -5)

y-1=-1/7(x+5)

Distribute -1/7 first

y- 1=-1/7x + 5/7

Add 1 on both sides, but since its a fraction add 7/7

y=-1/7x + (5/7+7/7)

y=-1/7x+12/7

3c+6=18 how do you work this problem?
Bogdan [553]

Answer:

c = 4

Step-by-step explanation:

Simplifying

3c + 6 = 18

Reorder the terms:

6 + 3c = 18

Solving

6 + 3c = 18

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + 3c = 18 + -6

Combine like terms: 6 + -6 = 0

0 + 3c = 18 + -6

3c = 18 + -6

Combine like terms: 18 + -6 = 12

3c = 12

Divide each side by '3'.

c = 4

Simplifying

c = 4

15+9=? (5+3) What number is missing from the expression?
Airida [17]

Answer:

<h3>\boxed{ \boxed{ \bold{  \mathsf{3}}}}</h3>

Step-by-step explanation:

Let the missing number be 'x'

⇒\mathsf{15 + 9 = x(5 + 3)}

Distribute x through the parentheses

⇒\mathsf{15 + 9 = 5x + 3x}

Swap the sides of the equation

⇒\mathsf{5x + 3x = 15 + 9}

Add the numbers

⇒\mathsf{5x + 3x = 24}

Collect like terms

⇒\mathsf{8x = 24}

Divide both sides of the equation by 8

⇒\mathsf{ \frac{8x}{8}  =  \frac{24}{8} }

Calculate

⇒\mathsf{x = 3}

Hope I helped!

Best regards!
