the width of the garden in feet. The entire garden is surrounded by a 5-foot-wide
cement walkway.

9

1- 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.2- 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 the first question?

Which of the following is an example of a rational number? a. π b. √ 9 c. √ 8 d. 3.8362319

Which of the following circles have their centers on the x-axis? check all that apply.
