Answer:
I think the answer is b^2=8^2-4^2
Step-by-step explanation:
The equation is A^2+B^2=C^2
C^2-A^2=B^2
C^2-B^2=A^2
C is the hypotenuse. You know what a is and all you have to do is show the equation

Answer:
10 miles per hour.
Step-by-step explanation:
Let x represent athlete's walking speed.
We have been given that her jogging rate is 5 mph faster than her walking rate, so athlete's jogging speed would be
miles per hour.

10 minutes = 1/6 hour.
20 minutes = 1/3 hour
While walking, we will get 

While jogging, we will get 

Since athlete is covering same distance while walking and jogging, so we can equate both expressions as:

Cross multiply:




Therefore, athlete's walking speed is 5 miles per hour.
Jogging speed: 
Therefore, athlete's jogging speed is 10 miles per hour.
