Final answer:
Option D, (2 = 12) = 5, cannot be rewritten using the associative property because it incorrectly uses the equals sign and is not a valid mathematical expression involving addition or multiplication.
Step-by-step explanation:
The associative property applies to the operations of addition and multiplication, which allows for the regrouping of numbers without changing the result of the operation. For example, in the expression (A+B)+C, we can regroup the numbers as A+(B+C) without changing the outcome.
Review of Options
The expression that cannot be rewritten using the associative property is option D, because it is not a case of addition or multiplication, but rather a misuse of the equals sign.
