Answer:
c. 1,464,843
Step-by-step explanation:
The sum of n terms of a geometric sequence with first term a1 and common ratio r is given by ...
sn = a1(r^n -1)/(r -1)
Filling in the values a1=3, r=5, n=9, we get ...
s9 = 3(5^9 -1)/(5 -1) = 1,464,843
Answer: c
105 x 4 = 420
63 x 7 = 441
420 + 441 = 861
poopppppppppppppppppppppeeeee
x = -7/2
( x + 9 ) - ( x -2 )=
2x +7 =
2x = -7
