Cathy wants to pack 100 gifts. The packaging includes a closed box made out of cardboard. The dimensions of the box are 11cm Long , 8cm wide and 8cm high. In square centimeters l, what is the minimum amount it cardboard Cathy needs to package all the gifts?

Step-by-step explanation:

l = Length = 11 cm

w = Width = 8 cm

h = Height = 8 cm

Perimeter of cardboard required for one box is

There are 100 gifts to pack so the total amount of cardboard needed would be

So, the minimum amount of cardboard Cathy needs to package all the gifts is .

78.59 is the mean

step-by-step explanation:

(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
