Mai solved the equation below incorrectly. Identify Mai's error. 3(x + 4) – 10 = 1/2(4x + 16)
3x + 12 – 10 = 2x + 8
3x + 2 = 2x + 8
5x + 2 = 8
5x = 6
X = 6/5

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?
