If f(x0 -x^2 + 6x - 1 and g(x) = 3x^2 - 4x - 1, find (f+g) (x) A. (f+g)(x) =2x^2 - 10x
B. (f+g)(x) = 2x^2 + 2x = 2
C. (f+g)(x) = -4x^2 + 10x
D. (f+g)(x) = 4x^2 + 10x +2

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
