Answer:
Step-by-step explanation:
Sure, here are the possible rearrangements of the word "mix" that have the parts proper in a:
* **mix** (the original word)
* **xim** (the letters are reversed)
* **imx** (the letters are rearranged)
* **mixs** (the letter "s" is added)
* **mixt** (the letter "t" is added)
However, none of these rearrangements have a specific meaning. The word "mix" is already a complete word, so there is no need to rearrange it to have the parts proper in a.
