Glven f(x) = x^2+ 2x - 1 and g(x) = 3x- 5; Determine f + g and f -9 F+g= F-g=

Step-by-step explanation:

you can find videos on yt for that

sorry, I'm not sure. you need a little more description though

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
