Which polynomial matches the expression -x(x – 5)? x2 – 5x x2 + 5x -x2 + 5x -2x – 5

-x2 + 5x

Step-by-step explanation:

See below.

The graphs are the same

the nearest power is 1.651.

means 7482 to the 1.651th power is almost equal to 2489287

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
