The surface area of the rectangular school gym floor is represented by the
equation below. When the expression is factored fully, the factors are the
dimensions of the floor. What are the dimensions of the floor? *
A= 120x2 + 1800x.
12x by x + 15
12x by 10x + 15
120x by x + 15
60x by 2x + 30

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
