What value should go in the empty boxes to complete the calculation for finding the product of 0.61 × 0.45? Both numbers are the same; however, only input the number one time in your answer.

It says factor each expression 49x-28?

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?

How do i simply this expression (quadratic formula basis) on a ti-84 or normal calculator?
