9 In a high-rise building there are 25 floors above ground floor (floor 1,
Aoor 2. ) and 6 floors below ground floor. A lift starts at floor 3 and
moves 5 floors down then 18 floors up, 4 more floors up, 26 floors down
and finally 6 floors up. At which floor does the lift finish?

Solve the equation 3x2 + 19x + 9 = 0 to the nearest tenth.

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

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?
