Monica and veronica are making strawberry pineapple smoothies. for every 112 cups of strawberries, they use 34 cups of pineapple. monica and veronica have already put 1 cup of pineapple into the blender. the girls cannot agree how many cups of strawberries to add to the blender to keep the same ratio, so they each did some work to determine the number of cups of strawberries necessary for the smoothie. monica’s work: 112÷3432÷3432×43422 veronica’s work: 34÷11234÷3234×232412 who has the correct work? a monica b veronica what did the other girl do incorrectly?

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

your answer is 125y5
