    The perimeter of the triangle is 4x+14

    Step-by-step explanation:

    Perimeter is sum of all sides.

    So,

    => 3x-5+2x+19-x

    => 5x-x-5+19

    => 4x+14

    So, The perimeter of the triangle is 4x+14

    4x + 14

    Step-by-step explanation:

    The perimeter of the triangle is equal to the sum of its three sides.

    The sides of the triangle are 3x-5, 2x, and 19-x.

    Calculate their sum.

    3x - 5 + 2x + 19 - x

    Rearrange.

    3x + 2x - x + 19 - 5

    Add or subtract like terms.

    4x + 14

    The perimeter of the triangle is 4x + 14.
