If f(×)=2x^2-5 and g(×)=3×+3 find (f-g)(×)a.3x-2x^2-2b.2x^2-3x-2 c.-x^2-7d.2x^2-3x-8

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
