Answer : B
the distance between the points (4,3) and (2,-1)
We apply distance formula

(x1,y1) is (4,3)
(x2,y2) is (2,1)


d^2 = 4+16 = 20
Take square root on both sides
So 
the distance between the points (4,3) and (2,-1) is 2sqrt(5)
Answer:
Step-by-step explanation:
Let number of hours be x
<u>Lakeshore paddle cost:</u>
<u>Lake paddle cost:</u>
<u>Required inequality:</u>

- 12x - 10x > 4
- 2x > 4
- x > 2
Lakeshore paddle costs less when time of rent is greater than 2 hours
