Answer:

Quotient: 2x^2+x-3

Please see the attachment.

Step-by-step explanation:

Given: (2x^4-3x^3-3x^2+7x-3)\div (x^2-2x+1)

We are given rational expression and need to find quotient.

Using long division method to find the quotient.

First we get rid of 2x^4 by x^2

x^2-2x+1 ) 2x^4-3x^3-3x^2+7x-3 ( 2x^2+x-3

                 -2x^4+4x^3-2x^2

                              x^3-5x^2+7x

                               -x^3+2x^2-x

                                      -3x^2+6x-3

                                      3x^2-6x+3

                                              0

Hence, The quotient of division is 2x^2+x-3

Here you have two polynomials:

1. The dividend - f(x)=2x^4 - 3x^3 - 3x^2 + 7x - 3

2. The divisor - g(x)=x^2 - 2x + 1.

Since divisor is perfect square g(x)=x^2 - 2x + 1=(x-1)^2, you should check what is the quotient after division f(x) by (x-1):

f(x)=2x^4 - 3x^3 - 3x^2 + 7x - 3=(x-1)(2x^3-x^2-4x+3)=(x-1)(x-1)(2x^2+x-3)=(x-1)^2(2x^2+x-3)=g(x)(2x^2+x-3).

Then the quotient is 2x^2+x-3.

17.8 multiplied by 2 is 35.6
9.5 multiplied by 2 is 19
Now you take both of them and add them together.
35.6 + 19 = 54.6 

Your answer should be 54.6 inches of ribbon.

Hope this helps.

Answer:

70%

Step-by-step explanation:

The number of students with an April birthday and candles is in the upper left, 14. That’s the “part” Percentage is part/whole x 100.

To figure out the “whole”, you need to add up all the students in the first row of the table, because those are the April birthdays. 14 + 6 = 20

14/20 = 0.7 x 100 = 70%
