AND 40 PIONTS A experiment was conducted, and it was determined that as the amount of sunlight increased, the height of the plants increased. Which of the following best describes this situation? Based on the data, this is an example of correlation and causation. Based on the data, this is an example of correlation. Based on the data, this is an example of causation. Based on the data, this is not an example of causation or correlation.

(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

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.
