= 1.75
Here,
(x+2)^1/2=3
raising power 2 on both sides,
x+2=9
therefore,
x=7
I think the answer would be 119 if I did it right
Using the arrangements formula, it is found that there are 40,320 ways for these swimmers to finish.
<h3>What is the arrangements formula?</h3>
The number of possible arrangements of n elements is given by the factorial of n, that is:

In this problem, there are n = 8 swimmers, hence they can finish arranged in 8! ways, that is:
