Erin's cat ginger likes to eat. The veterinarian as concerned about ginger's weight and put the cat on a strict diet. Over a six month period, ginger's weight decreased fro, 22lbs. to 16.5 lbs. Calculate the percent change

-25%

Step-by-step explanation:

Tow calculate the percentage change we need the difference in mass:

16.5 - 22 = -5.5 : Now we need to divide by the original amount and then multiply by 100:

-5.5 ÷ 22 = -0.25

-0.25 × 100 = -25%

(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

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
