PLEASE HELP
A quadratic equation is shown:

x2 − 8x + 13 = 0

Which of the following is the first correct step to write the above equation in the form (x − p)2 = q, where p and q are integers?

A) x2 − 8x + 13 − 5 = 0 − 5
B) x2 − 8x + 13 − 3 = 0 − 3
C) x2 − 8x + 13 + 5 = 0 + 5
D) x2 − 8x + 13 + 3 = 0 + 3

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
