Question 731859
I am trying to figure out the commutative and/or associative law of multiplication to write two expression equivalent to 
4(5x+8+3p) 
4(5x+3p+8) 
What I did i swap places. To solve I 4+8=12+3=15x5 =75x
4+3=7+8=15x5= 75x
-------------------
4(5x+8+3p) and 4(5x+3p+8) are the same.
----
= 20x + 12p + 32 or 12p + 20x + 32

Your answer has no p term.  I don't know exactly what you did, but it's not right.
