    Answer:

    P = 5x – 2

    Step-by-step explanation:

    Givens

    P=s1 + s2 + s3

    • s1 = 3x
    • s2 = x – 4
    • s3 = x + 2

    Solution

    • P = 3x + x – 4 + x + 2
    • P = 5x – 2

    Answer:

    Step-by-step explanation:

    The perimeter is just the sum of all side lengths so

    P=3x+(x-4)+(x+2)

    P=3x+x-4+x+2

    P=5x-2
