x = -3, 0, 2

Step-by-step explanation:

=> x³ + x² - 6x = 0

=> x(x² + x - 6) = 0

=> x² + x - 6 = 0 or x = 0

=> x² + 3x - 2x - 6 = 0 or x = 0

=> x(x + 3) - 2(x + 3) = 0 or x = 0

=> (x + 3)(x - 2) = 0 or x = 0

=> x = - 3 or x = 2 or x = 0

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
