-15
Reason:
First, use the distributive property
3(2p - 5) - 6p = 6p - 15 - 6p = -15
Answer:
Option D
Step-by-step explanation:
In this question we use properties of parallelogram and angle sum property of a triangle.
In parallelogram ABCD

As, we know that opposite angles of parallelogram are equal
Therefore,

Now, in triangle ADC
We know that sum of all the angles of a triangle is 



Subtracting 97 from both sides we get


Measure of 
You need to expand the brackets on both sides and then you can break it down
15x-6=-90
explore how the values of algebraic expressions like100-x,5/x+5,and
(3y) / (2y) change as the values of the variables change.
