Using the formula d=rt, which of the following statements is not true? Of = 5 and t= 3, then d = 15.
of r = 3 and t=5, then d = 8.
If r= 3 and t= 4, then d = 12
If r= 4 and 1= 2, then d = 8.

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?
