Supply the reason.

Afarmer has a large field that is x feet in length. he wants to fence in a rectangular section in the middle of the field , leaving a length of 100 feet of open field behind each end of the fenced rectangle. he also wants the width of the fenced-in space to be 100 feet less than its length. find the expressions to represent the length and width of the fenced section of the field

Since we have computer algebra systems that can solve polynomial division problems for us, why is it necessary to learn how to do these things by hand?

Agatorade cooler has 36 cups of water. if a serving is 3/4 of a cup how many servings are in the cooler?
