Answer:
a. T² - T¹ = d ( A. P) -5
b. T²/T¹ = r (G. P) 3/4
Step-by-step explanation:
a. 15 - 20 = -5
b. 15/20 = 3/4
3, 4, 5
3 ^2 = 9
4 ^2 = 16
5 ^2 = 25
9 + 16 = 25
if your considering 1 each, 20.
1 goes into 20,20 times
although....its 2021 now so I dont know (answer: 20).
the coefficient is A.5
78 i believe
4
4*4=16
(4+8)4=48
16*3=16!
