Answer:
B
Step-by-step explanation:
First, let's rearrange the given equation into something more recognizable. If we add 13 to both sides, we now have the polynomial 
. We can now use the quadratic formula to solve.
Remember that the quadratic formula is
Substitute the numbers from the equation into the formula.
Simplify:
Here, I'm going to assume that there was a mistype in option B because if we divide out the 2 we end up with 
.
Hope this helps!

Answer:
C
Step-by-step explanation:
Since there are two arcs and they both make up a circle, and a circle has 360 degrees.
NPL+NL=360
The measure of NPL is twice the measure of NL so
it now
2NL=NPL
Substitute that in the equation
2NL+NL=360
3NL=360
NL=120
Since NL subtends NML they are equal so NML=120
The answer you get will pretty much already have a zero in it ...so thats why
