Work out the missing percentages in these problems. See if you can spot the impossible problem which cannot be answered!

please read the explanation :)

Step-by-step explanation:

Make the precent a whole number then subtract it form 100 then the answer turn it to a percent :)

1) 100 - 65 = 35 = 35% of boys in the class

2) 100 - 27 = 63 = 63% of skirts that are not red

3) 100 - 78 = 22 = 22% non swimmers

4) 100 - 43 = 57 = 57% what he got wrong

5) 100 - 45+42 = 13 = 13% the games they tied

6) 100 - 28+35 = 37 = 37% who chose football

7) 100 - 38 = 62 = 62% are dogs

8) 100 -35 = 65 = 65% scored over average

9) 100 -12 = 88 = 88% percent

10) 100 - 6 = 94 = 94% can ride the bike

Hope that helps if you need more explanation please send me :)

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
