What is the leading coefficient of the polynomial f(x)f(x) defined below? f(x)=8x-8x^3-x^4+6 f(x)=8x−8x 3 −x 4 +6

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
