Describe shows how the total distance Jack has walked depends on the number of trips he has made to school what is the rate of change

the square root of what number? if you add that, then someone will probably answer the question.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
