Sherina wrote and solved the equation. x minus 56 = 230. X minus 56 minus 56 = 230 minus 56. X = 174. What was Sherina's error? Sherina's work is correct. Sherina only needed to subtract 56 from 230. Sherina made a subtraction error when subtracting 56 from 230. Sherina should have added 56 to both sides of the equation.

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?
