PLEASE ANSWER I NEED THIS HELP Quadrilateral WXYZ is a rectangle. If m∠XYW = 5x-7 and m∠RWX = 18 find the value(s) of x. Show your work for credit.

In the diagram below, dab and dac are adjacent angles. if mdac = 25°, what is mdab in degrees? what is mbac in degrees?

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?

Rewrite the following quadratic functions in intercept or factored form. show your work. y = x^2 + 7x + 10
