Answer:
D but see below.
Step-by-step explanation:
It can be factored if you are allowed to use square roots.
(p + 5√5)(p - 5√5)
Usually, you are not allowed to do that. Usually you must be working with whole numbers or rational well behaved fractions.
I think, given the above comment, the answer is D
It would be: 41/16.4 * 100 = 4100/16.4 = 250%
B. 4: for x-4
D. -6: for x-6
