  1. You can't expect someone from here to answer all these for you. If someone did you may get full marks in your work however when it comes down to a test you won't know any of it and that full marks will be useless.

    If you really don't understand how to do any of these questions you need to go to your teacher and ask or else look for some good maths websites and learn yourself. This stuff isn't all that difficult.

    However I will tell you that Qu9. has no real solution because

    6 x 6 = 36

    and

    -6 x -6 = 36

    Negitive numbers don't have "real" square roots.


  2. Bored enough to solve first 3.

    1. 504 gallons

    2. 0.29

    3. -50 or -34, forgot negative subtraction rules.

  3. I would love to see your face when you start calculus. These aren't hard, just think them through. In total, they should take you about an hour. Don't worry :) Try this website www.purplemath.com
