Given (x – 7)^2 = 36, select the values of x.

Step-by-step explanation:

We have been given an equation . We are asked to solve the given equation for x.

To solve our given equation, we will take square root of both sides of equation.

Therefore, the solution for our given equation are .

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

i can you answer this question sweetie!
