Answer:
B. Commutative Property of Multiplication
Step-by-step explanation:
I think that the answer is 2, because if you multiply two by each factor in the original photograph then you get the size of the new photograph.
P(5,2) = n! /(n-r)!
n = 5, r = 2:
= (5 x 4 x 3 x 2 x 1 ) / 3 x 2 x 1
Cancel out common factors:
= 5 x 4 = 20
The answer is 20.
