What is the solution to this equation?
whal
x-12 = 9
c
o a. x= 21
o b. x=-21
o c. x=-3
o d. x= 3

x-12 = 9

move -12 to the other side

sign changes from -12 to +12

x-12+12= 9+12

x=9+12

x= 21

A. x= 21

1e+27

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
