Mr. frame builds windows, he uses the function p=2l+2w to determine the perimeter of a rectangular-shaped window with length l units and width w units.
a) write the function, using function notation, that mr. frame can use to find the perimeter of any window with a length of 5 ft, given the width.
b) write the function, using function notation, that mr. frame can use to find the perimeter of any window with a width of 3 ft, given the length

What statement is true? 2x^2-9x+2=-1

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?
