Asteel company is making flat rectangular frames as a part of a new product they are launching. each frame will be cut out of a piece of steel and will have a final area as close to 28 cm2 as possible. the width of the frame needs to be uniform throughout. the inside dimensions of the frame must be 11 cm by 6 cm.
complete the equation that models the above situation, and find the width of the frame, x.
the area of the steel frame can be modeled by the following equation.
x2 +
x - 28 = 0
the width of the frame, x, rounded to the nearest hundredth, is approximately
cm.
