Use the zero product property to find the solutions to the equation x2 + 12 = 7x. x = –4 or x = 3
x = –4 or x = –3
x = –3 or x = 4
x = 3 or x = 4

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
