The Associative Property of addition states that the way in which numbers are grouped in an addition problem does not change the sum. It can be expressed as: (a + b) + c = a + (b + c).

To identify which option illustrates the Associative Property of addition, we need to find the one where the grouping of numbers changes but the sum remains the same.

A. The right side simplifies the terms but does not demonstrate the change in grouping, so it does not illustrate the Associative Property.

B. On the left side, we have x² + (4x² + 3x) :

We do not need to sim...
