Answer 1

`(14 + 7) + 12 = 14 + (7 + 12)`

Explanation:

Given

`(14 + 7) + 12` --- [Missing in question]

Required

Select equivalent expression

`(14 + 7) + 12`

Associative property states that:

`(a + b) + c = a + (b + c)`

In this case:

`a = 14`

`b = 7`

`c = 12`

So, we have:

`(a + b) + c = a + (b + c)`

`(14 + 7) + 12 = 14 + (7 + 12)`

B. is correct
