Michael invest $600 in an account with a 3% interest simple interest rate. The account is open for 10 years. How much interest did he earn after 10 years? A: $150
B: 180
C: 18000
D: 1800

$180

Step-by-step explanation:

Interest = Principal * rate * time

             = 600 * .03 * 10

             = 180

Principal + Interest = Total value

     $600 + $180 = $780

(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
