1. what does this illustrate? 2(3)=6, so 6=2(3) a. associative b. commutative c. reflexive d. symmetric e. transitive 2. if 3(3)=9 and 9=4+5, then 3(3)=4+5 **same a, b,c, d or e** 3. 7+4=4+7 **same a, b,c, d or e** 4. 4+7-2=4+7-2 **same a, b,c, d or e** 5. (2•3)•4=2•(3•4) **same a, b,c, d or e** ! only answer if you know the no fakes

1.  Commutative property is the eon that says it doesn't matter what order to multiply of add numbers.

2.  This is Transitive which is is a=b, and b=c the a=c

3.  the same as 1

4.  this is the same things, its not a  property its unchanged

5.  In this one you see has 2 and 3 and associated on the left and 3 and 4 on the right so it associates them differently but keeps the answer the same.  

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
