Theorem: Tangent segments from the same external point are congruent
So the two expressions you can set equal to each other
3x+10= 7x-6
-3x -3x
10= 4x-6
+6 +6
16= 4x
X=4
Answer:
3.9375
Step-by-step explanation:
Let's assume there's a fourth place too, and fourth place is the one where it's no prize.
4 3 2 1 (4 3 X X)
4 3 1 2 (^ but 3rd and 4th digit exchanged)
4 2 3 1 (4 2 X X)
4 2 1 3 etc.,.
4 1 2 3
4 1 3 2
As you can see, there are six possibilities assuming first swimmer was fourth.
Now, there would be six possibilities if the first swimmer was third, and same goes for second and first.
Thus, 6 x 4 = 24, there are 24 possibilities to award the 3 prizes (plus 1 no-prize)
Simple Mathematical Way:
4 x 3 x 2 x 1 = 4! = 24
There are 24 ways.
- The domain is any natural number.

Explanation:</h2>
The arithmetic sequence is defined as Follows:
<em>A sequence of numbers whenever the difference of any two successive members of the sequence remains constant.</em>
The explicit equation of any arithmetic sequence can be written as follows:
So here we know:
- First term is 5
- Second term is 3
Finally, the explicit formula is:
Moreover, the domain is any natural number.
