A rectangle has a height of t? + 7t +6 and a width of 2t + 1.
Express the area of the entire rectangle.
Your answer should be a polynomial in standard form.

2t^3+15t^2+19t+6

Step-by-step explanation:

(t^2+7t+6)(2t+1)

=t^2*2t+t^2*1+7t*2t+7t*1+6*2t+6*1

=2t^3+15t^2+7t+12t+6

=2t^3+15t^2+19t+6

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

1.true 2.false? ? i think. .
