    Exclamation Hellllpppp!! Please

    ^ and the number represents a number
    -------------------------------------

    (6a^3 - 5a^2 + 10a - 3) divided by (3a - 1)

    -------------------------------------

    (10x^3 - 3x^2 - 6x -4) divided by (5x - 1)

    -------------------------------------

    Use the formula A= lw and long division to find l when A = 10a^3 + 22a^2 - 2a - 12 and w = 2a + 4

    -------------------------------------

    thanks so much!

    Hello, omgitzbella!

    You need to learn/practice long division . . .



    3a - 1)" alt="(6a^3 - 5a^2 + 10a - 3) \:\div \3a - 1)" />
    Code:
                    2a -  a  + 3
            ---------------------
     3a - 1 ) 6a - 5a + 10a - 3
              6a - 2a
              ---------
                   -3a + 10a
                   -3a +   a
                  -----------
                           9a - 3
                           9a - 3
                          -------
