    Answer:

    The answer would be 5 inches for the width and 2 inches for the length of the rectangle.

    Step-by-step explanation:

    The first step would be to write an equation:

    2x+ 2(x-3) = 14 inches

    Next do the distributive property:

    2x+ 2(x-3) = 14 inches —> 2x+ 2x-6 = 14 inches

    After that, combine like terms:

    2x+ 2x-6 = 14 inches —> 4x-6 = 14 inches

    Then, add 6 to both sides:

    4x-6 = 14 inches —> 4x-6+(6) = 14 inches+(6) —> 4x = 20 inches

    Following this, divide both sides by 4:

    4x = 20 inches —> 4x÷(4) = 20 inches÷(4) —> x = 5 inches

    You now have the side length of the rectangle’s width.

    Lastly, find the length.

    5 – 3 = 2 inches

    To double-check, check with the equation.

    2x+ 2(x-3) = 14 inches —> 2(5)+ 2(5-3) = 14 inches —>

    2(5) +2(2) = 14 inches —> 10+4 = 14 inches —> 14=14 inches

    The answer is correct.
