Triangle mnl undergoes a dilation centered at the origin. the result is the green triangle. which rule describes the dilation? a) (x, y) → (5x, 5y) b) (x, y) → (3x, 3y) c) (x, y) → ( 1 5 x, 1 5 y) eliminate d) (x, y) → (−5x, −5y)

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?
