The length of a rectangle is (x+2) inches. The width of the rectangle is (x+1) inches.

Write an equation that can be used to determine the area (A) of the rectangle in terms of x.

What is the value of x if the area of the rectangle is 56 square inches?

  • Algebra -

    (x+1)(x+2) = A
    x^2 + 3 x + 2 = A

    x^2 + 3 x + 2 = 56

    x^2 + 3 x - 54 = 0

    (x+9)(x-6) = 0

    x = 6

    this is very stupid
