Which of these expressionis is <br> equivalent to x^4-5x+3/x^2+7
bonufazy [111]

Next time, please list the possible answer choices.  Without them, all I can do is to attempt this problem without having those choices as guidelines.


I must assume that your expression x^4-5x+3/x^2+7 actually meant:

            5x + 3

x^4  -  ---------------

             x^2 + 7

and I assume that this result was one of the several possible answer choices.

<em>h</em> = - 16(2.5)² + 80(2.5) = - 100 + 200 = <em>100 ft</em>.
