Your answer is 7x+11
You take away the 6-6 which turns into 0 and after you can’t do anything with the 7x but you add the terms 7 and 4

(x^3-8x^2+19x-9)\div(x-4)=x^2-4x+3\\\underline{-x^3+4x^2}\\=-4x^2+19x\\\underline{\ \ \ \ \ 4x^2-16x}\\.\ \ \ =3x-9\\\underline{\ \ \ \ \ -3x+12}\\.\ \ \ \ \ =\ 3

x^3-8x^2+19x-9=(x^2-4x+3)(x-4)+3

4/9÷1 7/15
guajiro [1.7K]

9514 1404 393

Answer:

  10/33

Step-by-step explanation:

The usual approach (if your calculator won't do this for you) is to convert the mixed number to an improper fraction, then perform the division. That division can be accomplished by multiplying the numerator by the inverse of the denominator.

  1 7/15 = (15+7)/15 = 22/15

Then ...

  (4/9)/(22/15) = (4/9)(15/22) = (2·2·3·5)/(3·3·2·11) = (2·5)/(3·11) = 10/33

_____

<em>Alternate solution</em>

Both fractions can be given the same denominator:

  4/9 = 20/45

  1 7/15 = 22/15 = 66/45

Now, the division is ...

  (20/45)/(66/45) = 20/66 = 10/33
