Read the excerpt from "With the Photographer" by Stephen Leacock. Select the correct answer from each drop-down menu. "I want my photograph taken," I said. The photographer looked at me without entusiasm . He was a drooping man in a gray suit, with the dim eye of a natural scientist. I began to see that I had done an unwarrantable thing in breaking in on the privacy of this man's scientific pursuits with a face like mine. The photographer rolled a machine into the middle of the room and crawled into it from behind. He was only in it a second,—just time enough for one look at me,—and then he was out again, tearing at the cotton sheet and the window panes with a hooked stick, apearantly frantic for light and air.

step-by-step explanation:

(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
