As well all know, evolution is a VERY VERY slow process. Do you think its possible that the human body is still evolving and still changing. Seriously.....Look at the bodies of women especially 100 years ago, and then today. What do you guys think?

I have an assignment and i got stuck on this question.... please help me if you can.... all what's required is a small pseudocode for the problem....

Write an algorithm that computes the length of the third side of a right triangle given the lengths of the other two sides.

Input: x,y (the lengths of two sides), and w (if w = 0, x and y are the legs; if w = 1, either x or y is the hypotenuse)
Output: z (the length of the third side)

ok so my science teacher told me to find the answer this but i have no idea how...
ok so the problem goes
lusia conducted an experiment to determine the relationship between distance and the brightness of stars. She used a meterstick, a light meter, and a lightbulb. She placed the bulb at the zero end of the meterstick, then placed the light meter at the 20 cm mark and recorded the distance and the light- meter reading in her data table. readings are in luxes. luisa then measured the light intensity. luisa incread the distance from the bulb to the light meter and took more readings.
data [effects of distance on light]
distance(cm) meter reading (luxes)
20 4150.0
40 1037.5
60 461.1
80 259.4
10 ?????
what would be the light intensity for 10 cm???

8-3( p-4) = 2p
i got 7.3
what i did was do
8-3p-12=2p
3p-20=2p
then i added 20 to 2p and got 22
then divided it by 3p so i got 7.3 is that right??
