Answer:

6

Step-by-step explanation:

You can use Ruffini's rule to divide x^3 − 7x^2 − 18^x + 42 by x + 3 as follows :

   | 1   -7   -18   | 42

-3 |     -3    30  | -36

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

   | 1   -10   12   |  6

Then (x^3 − 7x^2 − 18^x + 42) : (x + 3) = (x^2 - 10x +12)*(x + 3) + 6

A realtor makes a commission of $11,400 on a $190,000 house he sells. What is his commission rate?
Reika [66]
So bassically
his commision rate is
x% times 190000=comission
so x% times 190000=11400
divide both sdies by 190000
x%=11400/190000
solve for x percent
11400/190000=114/1900=3/50
x%=3/50
percent means parts out of 100 so x%=x/100
x/100=3/50
3/50=6/100
x/100=6/100
multiply both sdies by 100
x=6

the commision rate is 6%
