After arianna completed some work, she figured she still had 78 21/100 pictures to paint. if she completed another 34 23/25 pictures, how many pictures did arianna still have to paint Plz be a long answer

43 29/100

Step-by-step explanation:

Subtract 34 23/25 from 78 21/100.

To do this, you have to turn 23/25 to something over 100.

Multiply the numerator and denominator by 4, since that is how you get 25 to 100. This will give you 92/100. So now you have 32 92/100

You have to take away one from 78, which makes it 77 and then add 100 to 21, since 100 is equal to 1.

You now have 77 121/100 - 32 92/100.

77 121/100 - 32 92/100 = 43 29/100

(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

1) is right
