How do you divide polynomials using long division
levacccp [35]
This is a simple example:-
             x   +   9
         ------------------------------
x - 1 )  x^2  +  8x  -    9
           x^2  -   x                  subtract
           ------------
                     9x  -  9
                     9x  -  9
                  ----------
                     ..........

First divide x into x^2  to give x which goes above 
Then multiply x - 1 by x to give x^2 - x

Subtract this fro x^2 + 8x  gives 9x
Bring down the - 9 then divide x into 9x
and finally  multiply x - 1 by  9 to give   9x - 9
Finally subtract  and you sre done. There is no remainder as x - 1 is a factor of x^2 + 8x - 9.

The  polynomial must be in descending powers of x . If one is missing you insert it  with a coefficient of zero before you start the division. 

for example if you have   x^3 - 3x + 12   you write it as

 x^2 + 0x^2 - 3x + 12

Can you help me how to solve this problem ? thank you

Since BCDEF is regular, we know right away that x=\dfrac{360}5=72 because the measures of all exterior angles of any regular polygon add to 360 degrees; they are all of equal measure here, so we divide 360 by 5.

For the pentagon BCIHG, the same is true, which means we have the equation

\underbrace{72}_x+\underbrace{72}_{\angle_{ext}BCD}+\underbrace{90}_{\angle_{ext}CIH}+\underbrace{(180-y)}_{\angle_{ext}IHG}+\underbrace{68}_{\angle_{ext}HGB}=360\implies y=122

So x+y=194.

jeff used 3 cups of sugar to make 60 cookies. how many cups of sugar does he need to make 100 cookies?
Natasha2012 [34]

Answer:

5 cups of sugar

Step-by-step explanation:

To make 60 cookies you need 3 cups of sugar.

If you divide 60 / 3 you get 20.

That means: 1 cup = 20 cookies

Therefore to make 100 cookies you need 5 cups of sugar!
