Answer:
AC = 25
Step-by-step explanation:
The product of the near and far distances from C to the circle is the same for each segment. For segment CD, the near and far distances are the same. So, we have ...
CD² = CB·CA
CA = CD²/CB = 15²/9 = 25
The length AC is 25 units.

It seems possible that in some other versions of this question you might be asked to find x. Then you have ...
AB = AC -BC = 25 -9 = 16
3x +1 = 16 . . . substitute for AB
3x = 15 . . . . . subtract 1
x = 5 . . . . . . . divide by 3
Answer:
it's answer is D 123
Step-by-step explanation:
Here
88 - ( -35)
When it comes our of bracket - *- = +
So
88 + 35
= 123
Hope it will help you :)
Answer:
n=-3
Step-by-step explanation:
2-2n=3n+17
Add 2n to each side
2-2n+2n=3n+2n+17
2 = 5n+17
Subtract 17 from each side
2-17 = 5n+17-17
-15 = 5n
Divide by 5
-15/5 = 5n/5
-3 =n
