Short Answer: n = 5
The chords bear the relationship of (in this case)
18*(n + 1) = 9 * (n +7) Remove the brackets
18n + 18 = 9n + 63 Subtract 9n from both sides.
18n - 9n + 18 = 63
9n + 18 = 63 Subtract 18 from both sides.
9n = 63 - 18
9n = 45 Divide by 9
n = 45/9
n = 5 <<<<<<<< Answer

Answer:
5 : 1
Step-by-step explanation:
From your second-grade memorization of multiplication tables, you recognize that 15 = 3×5, so you know 3 is a factor of both numbers in the ratio. To reduce the ratio to simplest form, you divide out all common factors:
15 : 3 = (15/3) : (3/3) = 5 : 1
It can be solved by factoring or taking the root of both sides.
x= 2 radical 3. and -2 radical 3
