Type the correct answer in each box. Use numerals instead of words. A steel 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
x - 28 = 0

The width of the frame, x, rounded to the nearest hundredth, is approximately ___
