A rectangle has a height of 3 and width of 3x^2+ 4
what is the area?

9x² + 12

Step-by-step explanation:

Area  = Length × Width

Area = 3 × (3x² + 4)

Area = 9x² + 12

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
