Blow this up with random comments.

Ok.

Joke: You know you can't sleep in my class.

Response: I know. But if you were just a little quieter, I could.

Joke: On the first day of school, the teacher asked a student, "What is your name?" The student replied, "My father's name is Laughing and my mother's name is Smiling." The teacher said, "Are you kidding? The student said, "No Kidding is my brother. I am Joking."

Can I have brainliest pls. I am trying to reach a goal. I sent you a friend request.

hi

Step-by-step explanation:

kk

(b) 240

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
