5. The area of the square below is represented by the expression 4x2 + 4x + 1. The area of the rectangle is represented by the expression x2 - 5x + 6. Using the
diagram below, find the area of the shaded region.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
