SOLUTION: Find the property (APA,APM,CPA,CPM,DP,IP)of each of the changes: 5(n+4)+(-4n) =(5n+20)+-4n (5n+20)+(-4n) =5n+(20+-4n) 5n+(20+-4n) =5n+(-4n+20)

Question 1015283: Find the property (APA,APM,CPA,CPM,DP,IP)of each of the changes:
5(n+4)+(-4n)
=(5n+20)+-4n
(5n+20)+(-4n)
=5n+(20+-4n)
5n+(20+-4n)
=5n+(-4n+20)

5(n+4)+(-4n)
=(5n+20)+-4n...............Distributive Property (DP)
(5n+20)+(-4n)
=5n+(20+-4n)..........Associative Property of Addition (APA)
5n+(20+-4n)
=5n+(-4n+20)........Commutative Property of Addition (CPA)
