(2x3)^2 x -8 - 4(4 +10)^2 +8

= 4 (9x^3 - 196)

Step-by-step explanation:

Apply exponent rule,

Rewrite,

Factor out common term 4,

Refine,

2.83941151 would be the answer you're looking for! : )

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
