Louise uses 7.2 pints of blue paint and white paint to paint her bedroom walls. 1 4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?

Louise used 5.4 pints of white paint to paint her bedroom wall.

Step-by-step explanation:

Given:

Total amount of paint used = 7.2 pints

Amount of Blue paint =

We need to find the how many pints of white paint did she use to paint her bedroom walls.

Solution:

Amount in pints of Blue paint =

Now we can say that;

Amount in pints of white paint is equal to Total amount of paint used minus Amount in pints of Blue paint.

framing in equation form we get;

Amount in pints of white paint =

Hence Louise used 5.4 pints of white paint to paint her bedroom wall.

(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

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
