Answer:

[tex](14 + 7) + 12 = 14 + (7 + 12)[/tex]

Step-by-step explanation:

Given

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

Required

Select equivalent expression

[tex](14 + 7) + 12[/tex]

Associative property states that:

[tex](a + b) + c = a + (b + c)[/tex]

In this case:

[tex]a = 14[/tex]

[tex]b = 7[/tex]

[tex]c = 12[/tex]

So, we have:

[tex](a + b) + c = a + (b + c)[/tex]

[tex](14 + 7) + 12 = 14 + (7 + 12)[/tex]

B. is correct
