In order to compare the distances, we have to change them into one type of unit,
so, 4 Km = 4,000 m
We know,4,000 > 700
In short, Jessica ran more than Kristy
Hope this helps!
To calculate this you need to imagine triangle which points are:
boat
Top of lighthouse
Bottom of lighthouse
That triangle has 90 degrees angle at bottom of lighthouse. That means that we can use trigonometry to determine length between boat and bottom of lighthouse
tan(25) = 89/x
x = 89/tan(25)
x = 190.86
after rounding, the answer is D, 191 feet
ANSWER

EXPLANATION
The given quadratic trinomial is

Comparing to the general quadratic trinomial:

We have a=1, b=10 and c=-8

The factors of -24 that adds up to 10 are -2 and 12.
We split the middle term to obtain;

Factor;

Factor further;

The last option is correct.
