On day one, a bacteria colony begins with 20 bacteria and the number of bacteria triples each day. Which explicit equation can be used to determine the number of bacteria after n days? A. a n = 3(20)n
B. a n = 20(3)n
C. a n = 3(20)n – 1
D. a n = 20(3)n – 1

65°

step-by-step explanation:

the total measure of a triangle is 180 degrees. 62 + 53 is 115.

180 - 115 = 65
