    The answer to your question is: side 3 = 2a + 6

    Step-by-step explanation:

    Data

    Triangle

    side 1 = 5a + 3 inches

    side 2 = 2a + 3 inches

    side 3 = ?

    Perimeter = 9a + 12

    Process

    Perimeter = side 1 + side 2 + side 3

    9a + 12 = (5a + 3) + (2a + 3) + side 3

    side 3 = 9a + 12 - 5a - 3 - 2a - 3

    side 3 = 2a + 6
