(x^2–x–4)multiplied by(x–5)
Sergio [31]

(x-5)(x^2-x-4) =x^3-6x^2+x+20

Step-by-step explanation:

Given polynomials are:

x^2-x-4\\and\\x-5

Both polynomials have to be multiplied. We will use distributive property for the said purpose

So,

(x-5)(x^2-x-4)\\=x(x^2-x-4)-5(x^2-x-4)\\=x^3-x^2-4x-5x^2+5x+20

Combining alike terms

=x^3-x^2-5x^2-4x+5x+20\\=x^3-6x^2+x+20

Hence,

(x-5)(x^2-x-4) =x^3-6x^2+x+20

Paula knits hats. The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has. The constant o
Greeley [361]

Answer:

The equation showing the relationship between the number of yards of yarn Paula has and the number of hats she can knit is ;

h = 42y

Step-by-step explanation:

Here, we want to write an equation;

From the question, we are told that the number of hats h that can be knitted is directly proportional to the amount of yarn in yards

Since it is a proportional relationship;

h = k * y

where k is the constant of proportionality given as 42

Hence;

h = 42 * y

h = 42y
