Using all of the digits 1-9 (1, 2, 3, 4, 5, 6, 7, 8, 9) in that order and the operations +, - create 4 different equations with a sum of 100. Remember. It has to be IN ORDER as in 123456789. You can connect the numbers to like 12+34+567 etc. You have to make 4 different answers.

Can (3,5 and square root 34) be sides on a right triangle?

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?
