1,3,4,5,6 are correct.
Rethink 2, you'll get it right.
Would it be E?
Let's go through each statement and determine which property is being demonstrated.
1. 3+2+1=1+2+3
This statement demonstrates the commutative property of addition, which states that the order in which numbers are added does not affect the result.
2. 3(1+4)=(3x1)+(3X4)
This statement demonstrates the distributive property, which states that multiplying a number by the sum of two other numbers is the same as multiplying the number by each of the two numbers separately and then adding the products together.
3. 9(5+6)=45+54
This statement also demonstrates the distributive property.
4. 9+(4+3)=(4+3)+9
This statement demonstrates the associative property of addition, which states that the grouping of numbers being added does not affect the result.
5. (9+7)+6=9+(7+6)
This statement also demonstrates the associative property of addition.
6. 5(a+7)=5a+35
This statement demonstrates the distributive property.
Based on this analysis, the correct answers are:
1. C - Commutative Property of Addition
2. E - Distributive Property
3. E - Distributive Property
4. A - Associative Property of Addition
5. A - Associative Property of Addition
6. E - Distributive Property
