Indicate which property is illustrated in Step 3
Step 1
5 + (12 + 5) + 0 = 5 + (5 + 12) + 0
Step 2
= (5 + 5) + (12 + 0)
Step 3
= (5 + 5) + 12
Step 4
= 10 + 12
A. distributive property
B. identity property of addition
C. associative property of addition
D. identity property of multiplication

Best ResponseYou've already chosen the best response.1we have 12+0=12 12 is the same as 12 does that sound like an identity or associative property?

Best ResponseYou've already chosen the best response.1and I meant to say 12+0 is the same as 12* associative property we are changing where the grouping symbols are

Best ResponseYou've already chosen the best response.0The identity property for addition tells us that zero added to any number is the number itself. Zero is called the "additive identity." The identity property for multiplication tells us that the number 1 multiplied times any number gives the number itself.

Best ResponseYou've already chosen the best response.0I know it's not multiplication. You are explaining step 2 (5 + 5) + (12 + 0) The question is about Step 3

Best ResponseYou've already chosen the best response.1yes!!! The identity property for addition tells us that zero added to any number is the number itself. Zero is called the "additive identity." This is equivalent to saying a+0=a The identity property for multiplication tells us that the number 1 multiplied times any number gives the number itself. a*1=a
