Answer:
0,-11
Step-by-step explanation:
-p^2 − 11p = 0
Factor out -p
-p( p+11) =0
Using the zero product property
-p =0 p+11 =0
p =0 p = -11
x = 4
First you combine like terms:
8 + 4x = 24
Then solve:
4x = 24 - 8
4x = 16
x = 16/4
x = 4
Answer:

The answer is B. Quadrant II
Just remember this concept instead.
Answer:
ABC = 65
Step-by-step explanation:
The sum of the angles of a quadrilateral are 360
2x-15 + x + 2x-15 +x = 360
Combine like terms
6x -30 = 360
Add 30 to each side
6x -30 +30 = 360+30
6x= 390
Divide by 6
6x/6 = 390/6
x=65
We want angle ABC
ABC = x
ABC = 65
