2. The following is a proof that shows (Sp) (49) is equivalent to 20pq. Fill in
each blank with either "Commutative Property" or "Associative Property
to indicate the property being used.
(5p)(42) = 5(p.4)
= 5(4.p)ą
= (5.4909)
= 20p

Myra took a picture of the sky one afternoon when two jet airplanes appeared to draw a pair of parallel lines with their vapor trails. the vapor trails from two other jets flying from another direction crossed over the parallel trails. she printed her picture and labeled the angles and lines. assume lines c and d are parallel and 2 measures 98°. which statements are true? check all that apply. 3 = 6 = 98° 3 = 14 = 98° 4 = 8 = 82° 4 = 12 = 82° 5 = 8 = 82°
