Hi. I believe in reincarnation. I think I used to be a wolf, snake, shark, and every single living thing in the world, even animals that we didn't discover yet. No, I'm not some weird goth freak! lol I just believe stuff like that. One of my favorite sayings is, "Anything's Possible." We probably don't know anything about the universe. Do you think reincarnation is possible? Thanks please reply!!

P.S. I think my best reincarnation form was as a wolf. Bye!! :)

i have a mathmatical question need answering. to get the ten points you must give me the answer and how you worked it out:

a person can do a job in 3 hours, another person can do the same job in 4 hours, and yet another person can complete the job in 6 hours. if they all worked together how long would it take to complete the job?

first correct answer wins the 10 points.

Does anyone find it difficult to believe that the universe goes on for ever? I don't believe the universe is infinite, but at the same time I find it difficult to comprehend what would be beyond the universe if it it did end. Also before the big bang what was there. Don't say nothing, because what is nothing? Don't say an empty space, because even an empty space is something.

Use synthetic division to decide whether 4+i is a zero
of f(x)= xsquared -8x+17

this is the answer: Since f(4+i) equals 0, 4+i is a zero of f(x)=xsquared -8x+17
