(X^3+1)dividend (x-1)
bazaltina [42]

x^3=x\cdot x^2 and x^2(x-1)=x^3-x^2. So we have a remainder of

(x^3+1)-(x^3-x^2)=x^2+1

x^2=x\cdot x and x(x-1)=x^2-x. Subtracting this from the previous remainder gives a new remainder

(x^2+1)-(x^2-x)=x+1

x=x\cdot1 and 1(x-1)=x-1. Subtracting this from the previous remainder gives a new one of

(x+1)-(x-1)=2

and we're done since 2 does not divide x. So we have

\dfrac{x^3+1}{x-1}=x^2+x+1+\dfrac2{x-1}

What is the value of y? Enter your answer in the box. y = An isosceles triangle with vertices labeled A, B, and C. Side B C is t
klasskru [66]

Answer:

The answer is y=20

Step-by-step explanation:

If you take a look at the attached picture you will notice that angles B and C are congruent, so that means they both are 25 degrees.

Next, add angles B and C together to get 50.

Then you take that 50 and add it to 70 in angle A's equation, and you will get 120.

Next, plug 120 into angle A's equation where the 70 was and you will have the equation 3y+120=180. (180 is there because that is what all the interior angles equal together.)

Next, slove the equation.

  1. 3y+120 = 180
  2.     -120   -120
  3.        3y = 60
  4.         /3   /3
  5.          y = 20

And theres your answer, I hope I helped. Put any questions in the comments.

Quadrilateral OPQR is inscribed in a circle as shown below...
kipiarov [429]
We can use the fact that a cyclic quadrilateral (i.e. a quadrilateral inscribed in a circle) has the opposite angles supplementary, therefore
2x+(2x+4) = 180
Solving for x:
4x+4=180 
4x=180-4=176
x=176/4=44 °
=>
angle O = 2x = 88 °  
angle Q=180-O=180-88 = 92 °

Similarly,
(3y+8)+y= 180
=> y=43 °
=>
P=y=43 °
R=180-43=137 °
