Answer:
3150
Step-by-step explanation:
The answer is 8 because when you replace x by 8 it equals 24
We have the representation of this problem in the figure below. As we have a 10.3 mile race, then the equation is fulfilled as:

We know that there is <span>a water station that is twice as far from the starting line as from the finish line, then:
</span>

So:

∴

and

<span>Finally, the distance of the runner from the finish line is:
</span>
It seems you tried to write √(-20)
use the fact tha -1 = i^2
Then, √(-20) = √(20i^2) =(√20) i = (√(5*4))i = 2√5 i = 2i√5, which seems to be what you tried to write in the option B.
