HEYOO PEEPS Should doctors be allowed to dress casually while at work? Why or why not? What is your opinion?

Yes, because they should be professional, in my personal opionion it should be like lawyers they have to waer suits and ties because it's what their job requires. So, doctors should have to wear scrubs because it's the professional thing to do and doctors and nurses get dirty very easily so they don't ruin their nice attire they should have to wear srubs.

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
