B. The answer is x = 6.
The midpoint of JK is
The line that goes through JK is just a horizontal line because the y-coordinate does not change. So its perpendicular bisector is the vertical line that goes through the x-coordinate of the midpoint, that is,
.
Answer:
C
Step-by-step explanation:
The n th term formula of a geometric sequence is
= a
where a is the first term and r the common ratio
Using the second and fourth term, then
ar = 6 → (1)
ar³ = 54 → (2)
Divide (2) by (1)
=
= 9
r² = 9 ⇒ r = = 3 → C
