Q. Which equation shows the associative property of addition?Choices:(A) (5+1)+2=5+(1+2)(B) 4=0+4(C) 12=4+8(D) 9+6=6+9
Identify Property Formula: Identify the associative property of addition formula: (a+b)+c=a+(b+c).
Check Choices: Check each choice to see if it matches the associative property formula:(A) (5+1)+2=5+(1+2) - This matches the formula.(B) 4=0+4 - This is not about grouping, it's an identity property.(C) 12=4+8 - This is just a simple addition, not about grouping.(D) 9+6=6+9 - This shows the commutative property, not associative.
