Find the complete factorization of the expression. −20xyz − 18xy − 4xz a) 2x(10zy + 9y + 2z) b) −x(20zy + 18y + 4z) c) −2x(10zy + 9y + 2z) d) −2(10xzy + 9xy + 2xz)

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

the correct answer is the second option
