Step-by-step explanation:
9m²+8m-6-7m²-3m+3
first write like terms
9m²-7m2+8m-3m-6+3
second ad subtract the terms
2m²+5m-3
factorize
2m²-m+6m-3
m(2m-1)+3(2m--1)
(m+3)(2m-1)
m=-3. m=1/2
The angles m∠x = m∠y because alternate interior angles are equal.
<h3>What is a
parallelogram?</h3>
A parallelogramis a quadrilateral in which opposite sides are equal and parallel to each other.
The opposite angles are also congruent, whereas consecutive interior angles are supplementary.
In the quadrilateral ABCD:
m∠x = m∠y (alternate interior angles are equal)
The angles m∠x = m∠y because alternate interior angles are equal.

By checking to see if there is correlation, Sam is evaluating the criterion validity of the metric.
<h3>How to determine the measured parameter of the metric</h3>
From the question, we understand that Sam tests the metric to check for the presence or absence of correlation in the metric.
This, in other words means that Sam is checking the criterion validity of the metric.
Hence, the true statement is that Sam is evaluating the criterion validity of the metric.
