B It’s the one that makes sense
In kilometers, the approximate distance to the earth's horizon from a point h meters above the surface can be determined by evaluating the expression

We are given the height h of a person from surface of sea level to be 350 m and we are to find the the distance to horizon d. Using the value in above expression we get:
Therefore, the approximate distance to the horizon for the person will be 64.81 km
N6+5=n-10
n6=n-15
n5=-15
n=-3
hope this helps:)
B) 40,000. the first 2 is 20,000. the second 2 is 2. 20,000 times 2 is 40,000
