What is the following product? (x StartRoot 7 EndRoot minus 3 StartRoot 8 EndRoot) (x StartRoot 7 EndRoot minus 3 StartRoot 8 EndRoot) 7 x squared + 72 7 x squared minus 12 x StartRoot 14 EndRoot + 72 7 x squared minus 12 x StartRoot 14 EndRoot minus 72 7 x squared minus 72

1- 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.2- 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 the first question?

A.s.a.! this is a similarity in right triangles. next (solve for x)a.) 12b.) 5c.) 12.5d.) [tex] 6\sqrt{3} [/tex]

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top
