Answer:
D is correct. 
Step-by-step explanation:
We are given the root of the equation

If we are given solution of the equation then find equation using formula.
If a and b are the solution of equation then equation would be (x-a)(x-b)=0
Here, 
Equation form would be 
Now we simplify the above equation to get correct option.


So, D is correct. 
Answer:
Step-by-step explanation:
e = 300-10(30)
e = 300 - 300
e = 0
It would be the same as measure of triangle RQP
Answer:
If asking for the distance, the answer would be C.
