What is the product of (6x^2 + 8)(3x^2 – 5x + 7)?

Solve x+3y=6 and 4x-6y=6 by elimination . show work !

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?
