Answer 2

Answer:

Well, I am not sure which one is equivalent to another, but I have some information that should help you find your answer.

Step-by-step explanation:

The simplified expression to x2 − x − 6 x2 + 2x − 15 would be equal to −5 x 2 + x − 15.

The simplified expression to x + 3 x + 5 would be equal to 4x + 5.

The simplified expression to x + 2x + 5 would be equal to 3x + 5.

The simplified expression x + 3 x − 3 would be equal to 4x − 3.

The last simplified expression to x + 2 x − 3 would be equal to   3x − 3.

Hope this helps, I am really sorry if I didn't answer your question properly, or the way you asked!
