Which expression is equivalent to 7-2z-4{z^3- z^3+4z^2+11z+14/z+2] -4z^3+4z^2+6z+35

-4z^3+4z^2-10z-21

-18z-5

-18z+10

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

correct me if i am wrong.
