Deeside weather the given number is a solution of the given equation. is 8 a solution of y + 9 = 17? yes or no. simplify the expression by combining like terms. 10x - x - 2x - x 8x x² + 8x 6x -x² + 8x

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
