Using the associative property, we can rearrange the terms in any way as long as the order of the operations does not change.
(9x + 3) + (2x - 10) can be simplified by rearranging the terms as follows:
9x + 2x + 3 - 10
Combining like terms, we get:
11x - 7
So, the simplest equivalent form of (9x+3)+(2x−10) is 11x - 7.
