If B = t + 10 and A = 3t2 – 2, find an expression that equals 2B-3A in standard form

4

step-by-step explanation:

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

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
