The rectangle below has an area of x^2-15x+56 x 2 −15x+56 x, start superscript, 2, end superscript, minus, 15, x, plus, 56 square meters and a length of x-7x−7x, minus, 7 meters. what expression represents the width of the rectangle

By definition, a rectangle is a quadrilateral (4-sided polygon) with two sets of parallel and equal sides called length and width. The area of a rectangle is equal to the product of these two. The equation for the area is a quadratic equation. When you factor out a quadratic equation, it would be a product of two binomials such as (x-q)(x-r) = 0, where q and r are roots or zero's of the equation. You can find this by using the quadratic formula:



where a, b and c are the coefficients and constant of the quadratic equation with a general formula of ax²+bx+c=0. Substituting to the equation:



x = 7,8

Therefore, the binomials are (x-7) and (x-8). Since it was mentioned that the length is (x-7), then the width is (x-8).

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67

Bwould be the answer
