Depends on your question...
If your question is r + 0.12 = 0.20 then do this:
Subtract 0.12 from both sides
r = 0.08
The answer is B.
If your question is r - 0.12 = 0.20 then do this:
Add 0.12 on both sides
r = 0.32
The answer is A
So it depends on your question :P
A Pythagorean theorem question is one that deals with the side lengths of a RIGHT triangle.
When solving a question you would use the formula, a^2 + b^2=c^2
A and B are both of the sides that aren’t the hypotenuse.
C is distinguishable from a and b as it is the side opposite from the 90 degree angle. (90 degree angles are formed by perpendicular lines)
Hope this helps :)

Answer:
k = 3
Step-by-step explanation:
Since p - 1 is a factor then p(1) = 0
p(x) = 
+ p² + p - k, thus
p(1) = 
+ 1² + 1 - k = 0, that is
1 + 1 + 1 - k = 0
3 - k = 0 ⇒ k = 3
