  • (12/t) + t = 8
    12 + (t^2) = 8t
    (t^2) - 8t + 12 = 0
    then solve
    (t - 2) (t - 6) = 0
    so t is 2 or 6

      Lol ok yeah. Got that right before you posted this. Thanks.

      One more?

      10 + ----- 2n-5 = 2n+5
      n^2-1 ----- n-1 -- n+1

      I apologize. I'm sure this is easy as well. I know I have to get the LCD.

      • I assume this is meant to be (10/(n^2)-1) + ((2n-5)/(n-1)) = (2n + 5) / (n+1)

        You need to rearrange n^2 - 1 to (n-1)(n+1), then multiply through the whole thing by (n - 1) and then (n + 1), once you have multiplied through you should have:

        10 + (2n-5)(n+1) = (2n+5)(n-1)

        multiply out the brackets and rearrange until you get an equation in the form a^2n + bn + c = 0, then solve.

          It does. The rearrangement is what was throwing me off.

                      • I have an English exercise which is an all or nothing grade. All I have to do is write 4 lines of dialogue between two people. I have to get it 100% correct in order to get the "E" grade(Excellent). So is this 100% perfect, and no comma, parentheses, periods, punctuation wrong? Thanks a ton. +Rep to whoever helps thanks. Here is the Dialogue:
                        --------------------------------------------------------------------------------
                        “Man, it’s really hot in here,” I said.

                        He grinned and said, “Wait ‘till you walk into the pressing room.”

                        “Oh really,”

                        “Yeah, really.” he said as he wiped the sweat off his brow.

                            Grammar is my worst subject, but 'Oh really' I think has a period due to it being purely dialogue.

                            And then yeah really should hae a comma, not a period.

                            It is my worse subject. So I may be wrong.

                            I probably seem pretty unintelligent in this thread. Oh well. I'm not (unintelligent that is).

                              I also think those are correct.

                                Instead of saying "Oh really", you have to put a ? after the really since it's a question.

                                No rep needed.

                                That's all I answered since the other two guys got it.
