The <em><u>correct answer</u></em> is:
A.associative property
Explanation:
The associative property tells us that we can move a set of parentheses around a problem if it is only addition/subtraction (treating subtraction as negatives) or multiplication.
All that has been done in this problem is that the parentheses have been moved around, so this is the associative property.

Answer:
x^2 -81
Step-by-step explanation:
(x+9)(x-9)
FOIL
first x*x = x^2
outer -9x
inner 9x
last -9*9 = -81
Add them together
x^2 -9x+9x -81
Combine like terms
x^2 -81
