Y -3 =9 solve for y 4w = 24 solve for w y -3 =9 solve for y

Danny draws a transversal, t, on two parallel lines ab and cd, as shown below: he makes the following table to prove that the alternate interior angles are equal: which is the missing justification? (6 points) corresponding angles formed by a transversal on parallel lines are supplementary. corresponding angles formed by a transversal on parallel lines are congruent. co-interior angles formed by a transversal on parallel lines are congruent. co-exterior angles formed by a transversal on parallel lines are congruent.

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)

Factor the polynomial. b^2 + 4b + 4
