Answer:
64
Step-by-step explanation:
So here you're just completing the square. the equation you gave is simply: 
where c is the unknown value we're solving for. Whenever you complete the square, you add (b/2)^2
The reason for this, is because whenever you write a binomial as a perfect square it's in the form: 
and this binomial expands out to become: 
If we write the second term of the binomial as b/2 we get:
which simplifies to:
and as you can see the last term is (b/2)^2, which is why we need to add that part for it to be a perfect square.
So we would need to add (16/2)^2 = 8^2 = 64
This way, we can express it as a perfect square binomial: 
which expands out to: 
Using the formula given: d = <span>√(3h/2)
We simply substitute the given values of h into the equation and compare the results.
For Wyatt where h = 120:
d = </span>√(3(120)/2)<span>
d = 13.42 miles
</span><span>For Shawn where h = 270:
d = </span>√(3(270)/2)<span>
d = 20.12 miles
</span>
Since the question asks for how much farther can Shawn see, we subtract the results:
20.12 - 13.42 = 6.7
Therefore, Shawn can see 6.7 miles farther.
