[10 POINTS] Name the algebraic property demonstrated in the example below:
(2 + x) + y = 2 + (x + y)

A. Commutative Property of Addition
B. Associative Property of Addition
C. Distributive Property
D. Transitive Property

Respuesta :

The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' I mean 'how you use parenthesis'.

In other words, if you are adding or multiplying it does not matter where you put the parenthesis.
 

Hence, the answer is B.

The answer is b because: Associative property means  involving the condition that a group of quantities connected by operators gives the same result whatever their grouping, as long as their order remains the same. so when you do (2 + x) + y = 2 + (x + y) the answer will remain the same when you do it backwards.
