what is the associative property of addition?

Question

a.(a x b ) x c = ax ( bx c )
b.(a + b) + c = a +(b+c)
c. (a+b) x c = a+(c+c)

2nd question

a.(a+b) + c=a + (b x c)
b.(a+b) + c =a x (b x c)
c.(a x b) x c =a x (b x c)

3rd question

b.6 + (4+2)= (6+4) +2
c. 6 + 9 +5=5+9+6

4th question
which of these illustrates the associative of multiplacation??
a.6 x (9x1)=(6x9)x 1
b. 6 x (91) = (69) x 1

c. b+ c

Answer 1

1 b
2 c
3 b
4 a
5 c
6 a
7 c
8 b
9 no answer, you must have mistyped.

Once you know the answers to 1 and 2, you should know the answers to the rest.

I don't feel like I helped you by giving you the answers to these. If you don't understand this well enough to answer these questions on your own, then you really need to talk to your teacher to get some extra help. This is about as easy as it gets when it comes to pre-algebra.
