Using the defects method, which of these relationships represents the Law of Cosines if the measure of the included angle between the sides a and b of ∆ABC is more than 90°? A.
area of square c2 = -area of square a2 − area of squareb2 + area of defect1 + area of defect2
B.
area of square c2 = area of square a2 + area of squareb2 + area of defect1 − area of defect2
C.
area of square c2 = area of square a2 + area of squareb2 − area of defect1 − area of defect2
D.
area of square c2 = area of square a2 + area of squareb2 + area of defect1+ area of defect2
E.
area of square c2 = area of square a2 − area of squareb2 + area of defect1 − area of defect2

(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

step-by-step explanation:

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
