Choose two axioms that allow 6 + (x + 5) to be written x + 11.
a) commutative - addition
b) distributive
c) associative - multiplication
d) symmetric
e) commutative - multiplication
f) associative - addition
g) identity - addition

Basic number properties:

The Distributive Property: The Associative Property for addition: The Associative Property for multiplication: The Commutative Property for addition: The Commutative Property for multiplication: Identity Property : Any number add to the zero the answer is the number itself;The symmetric property states that if one number is equal to a second number, then the second number is equal to the first number.

For the expression 6 + (x + 5):

use The Commutative Property for addition - 6+(x+5)=(x+5)+6;use The Associative Property for addition - (x+5)+6=x+(5+6)=x+11.
