Answer:

Step-by-step explanation:

Pull out like factors :

-12x + 72 = -12 • (x - 6)

Step 2 :

Equations which are never true :

Solve : -12 = 0

A non-zero constant never equals zero.

Solving a Single Variable Equation :

Solve : x-6 = 0

Add 6 to both sides of the equation :

x = 6

IgorLugansk [536]

Answer:

s ( x ) = 102, a ( x ) = 8 ( x + 2 )

f ( x ) = s ( x ) + a ( x ) = 102 + 8 ( x + 2 ) =

= 102 + 8 x + 16

final answer : f ( x ) = 8 x + 118

Find the distance between the points (3, 8) and (0,4).

Bingel [31]

Answer:

Step-by-step explanation:

(3,8) (0,4)

X1 = 3 X2 = 0

Y1 = 8 Y2 = 4

$D=\sqrt{(X1-X2)^{2}+ (Y1-Y2)^{2} }$

$D= \sqrt{(3-0)^{2} + (8-4)^{2} }$

Do what's in the parentheses so...

3-0= 3
8-4= 4

Now plug it in!

$D= \sqrt{(3)^{2}+(4)^{2} }$

Now you are going to finish the parentheses so...

(3)^2= 9
(4)^2= 16

Plug that in so that you have this...

$\sqrt{9+16}$

Add 9+16 to get...

$\sqrt{25}$

Then you are going to find the number or numbers that make this a perfect square...

$\sqrt{25}= 5$

So 5 is your answer
