1. π is irrational, so a multiple of π is also irrational.
2. -30.22 is a terminating decimal, so it is rational.
3. -sqrt(23): sqrt(16) = 4; sqrt(25) = 5. sqrt(23) is between 4 and 5 and irrational.

Answer:
19 units.
Step-by-step explanation:
Consider the below figure attached with this question.
From the below figure it is given that MN=PQ.
It is given that MP = 6x – 5, QR = 3x + 1, and RN = 6.
Since non parallel sides are equal, therefore it is an isosceles trapezoid.
The diagonals of an isosceles trapezoid are equal.
Substitute the given values.
The value of x is 4.
Hence, the measure of QN is 19 units.
