Use whichever properties (associative and/or communities) are necessary to simplify each expression.

(2+n)+9

(5+x+3)+2

(2+n)+9

(5+x+3)+2

(2+n) +9

=9+(2+n).... commutative property

=(9+2)+n ......associative property

=11+n Answer

(5+x+3)+2

=2+(5+x+3) commutative property

=(2+5) +(x+3) associative property

=7+ (x+3)

=(7+3)+x associative property

=10+x Answer
