send answer with explanation.

We know there are no squares between 100² and 101².

So we just want to know how many numbers between a and b exclusive, which is

n = b - a - 1

For example between 10 and 20 exclusive we get n=20-10-1=9, which is right.

For our problem here we can factor using the difference of two squares and get:

n = 101² - 100² - 1 = (101 - 100)(101 + 100) - 1 = 1(201) - 1 = 200

d. 200

there is no graph so i cant sorry

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
