Which polynomial function has a leading coefficient of 1 and roots (7 + i) and (5 – i) with multiplicity 1? f(x) = (x + 7)(x – i)(x + 5)(x + i) f(x) = (x – 7)(x – i)(x – 5)(x + i) f(x) = (x – (7 – i))(x – (5 + i))(x – (7 + i))(x – (5 – i)) f(x) = (x + (7 – i))(x + (5 + i))(x + (7 + i))(x + (5 – i))

Find the solution of each of the following.

Delbert keeps track of total of the total number of points he earns on homework assignments, each of which is worth 60 points. at the end of the semester he has 810 points. write an equation for delbert’s average homework score a in terms of the number of assignments n.

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
