Melissa is packing up her bedroom before she leaves for college. Her closet is 185 cubic feet. If the boxes she is using are 4 ½ feet long, 2 feet wide, and 4 feet high. How many boxes can she fit into her closet?

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

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?

Me. i can't figure out this question. give an explanation too. .
