If MP = 6x – 5, QR = 3x + 1, and RN = 6, what is QN?
NeTakaya

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.

MP=QN

MP=QR+RN

Substitute the given values.

6x-5=3x+1+6

6x-5=3x+7

6x-3x=5+7

3x=12

x=4

The value of x is 4.

QN=MP=6x-5=6(4)-5=24-5=19

Hence, the measure of QN is 19 units.
