Step-by-step explanation:
The geometric mean of 2 numbers a and b is 
, then
= 16
( square both sides )
28a = (16 )² = 1792 ( divide both sides by 28 )
a = 64

For two secants that intersect at a point outside the circle, the product
(segment outside the circle)(whole secant) is the same for both secants!
What's the length of the entire secant that has <em>x</em>'s on it? 6x + 8x = 14x.
What's the length of the entire secant that has 9 and 7 on it? 9 + 7 = 16
