loris [4]

Answer:

\frac{2x^2+5x-14}{x-2}=(2x+9)+\frac{4}{x-2}

Step-by-step explanation:

Given rational expression is,

\frac{2x^2+5x-14}{x-2}

x - 2) 2x² + 5x - 14(2x + 9

         <u>2x² - 4x</u>

                  9x - 14

                  <u>9x - 18</u>

                          4

Therefore, \frac{2x^2+5x-14}{x-2}=(2x+9)+\frac{4}{x-2} is the answer.

Answer:

<h2><u><em>15 is the answer.</em></u></h2>

Step-by-step explanation:

The side lengths are equal - supposedly

30                          25

?                              ?

25 + ? = 45

-25        - 25

? = 20

45 - 30 = 15

The question mark should be equal to 15.

Hope this helps,
