    89x² + 31x + 22

    Step-by-step explanation:

    3x² + 16x² + x + 7 (10x²) + 22 + 15x - 6x

    First we can distribute the 7 to the 10x² and now we have:

    3x² + 16x² + x + 70x² + 22 + 15x - 6x

    We have three x² terms so we can combine those:

    89x² + x + 22 + 15x - 6x

    We have three x terms and we can combine those:

    89x² + 31x + 22

    Nothing else can be done here and all of the terms are in descending order of powers
