State the property that justifies the statement. For example, $3 + ( - 4 ) = ( - 4 ) + 3$ because of the commutative property for addition. $- 3 + ( 9 - 2 ) = ( - 3 + 9 ) - 2$
A) Associative Property of Multiplication
B) Commutative Property of Addition
C) Identity Property of Addition
D) Distributive Property
E) Associative Property of Addition

The given expression can be simplified using the associative property of addition, which states that the grouping of numbers being added does not affect their sum. Therefore, we can add 9 and -2 first, and then add -3 to the result, or we can add -3 and 9 first, and then subtract 2 from the result. Both methods will give us the same answer, which is -2 + 6 = 4.

State the Property That Justifies the Statement 3+(−4)=(−4)+33 + ( - 4 ) = ( - 4 ) + 33+(−4)=(−4)+3

State the Property That Justifies the Statement $3 + ( - 4 ) = ( - 4 ) + 3$
