  1. wwwwwwwwwwwhhhhhhhhhhhhhhhhhhyyyyyyyyyyy aaaaaaaaarrrrrrrrrrrreeeeeeeee yyyyyyyyyyyyyyyyoooooooooooooooouuuuuuuu... writing like that? To begin I don't think people feel comfortable doing any of them. Also your grammar is very poor

    ALEGEBRA (Algebra, you spelt it wrong) 2 help please do as many as you know thanks to everyone?

    what the h**l! Where is the question in that "do as many as you know thank to EVERYONE?" are you questioning yourself thanking everyone. Lastly, how about you look this stuff up in your book or on the internet and get equations instead of answers. How lazy, this site isn't for doing homework. GO DO YOUR HOMEWORK.


  2. 7.  e³=1.099

  3. You're retarded.

  4. Isn't that your homework?

    I really LOVE to do those questions for you, but that is just cheating, those are your homework questions! At least do half of it so it shows you put some efforts in it.

    Those AREN'T hard! I'm probably youger then you according to the wordings, and yet I finished the WHOLE questions all by myself!

    Here's the EASIEST:

    #17 Answer: 1225

    My figured out equation: x/2(x-1)

    Let x stand for the known numbers, like 50 is your number.

  5. 1. (h+3)(h+4)
