Absolute value inequalities:
4|8y+7|-9 < 91

The factorization of 8x3 -125 is (2x-5)(jx2 +kx+25)

If eh = hg and hg=16, find the diameter of k

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?
