For a regular n-gon:
a. what is the sum of the measures of its angles?
b. what is the measure of each angle?
c. what is the sum of the measures of its exterior angles, one at each vertex?
d. what is the measure of each exterior angle?
e. find the sum of your answers to parts b and d. explain why this sum makes sense.

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
