The polynomial p ( x ) = x 3 − 7 x − 6 p(x)=x 3 −7x−6p, left parenthesis, x, right parenthesis, equals, x, cubed, minus, 7, x, m
avanturin [10]

Answer:

p(x)=x^3-7x-6 = (x+1)(x+2)(x-3)

Step-by-step explanation:

Given that polynomial:

p(x)=x^3-7x-6

Known factor: (x+1)

To find:

Equation of the polynomial as the product of linear factors.

Solution:

The degree of polynomial is 3, and when we divide it by a linear equation, the result will be a quadratic.  That quadratic will have 2 solutions.

We can solve the quadratic in two linear factors and as a result we will have the answer.

First of all, we need to divide the polynomial p(x) with the given factor (x+1) to find the other factors.

\dfrac{x^3-7x-6}{x+1} = x^2-x-6

Solving the quadratic:

x^2-x-6 = x^2-3x+2x-6\\\Rightarrow x(x-3)+2(x-3)\\\Rightarrow (x+2)(x-3)

So, the answer is:

p(x)=x^3-7x-6 = (x+1)(x+2)(x-3)

In a recent awards​ ceremony, the age of the winner for best actor was 35 and the age of the winner for best actress was 54. For
Arada [10]

Answer:

The actress has the more extreme age because

Step-by-step explanation:

Given

Male Athletes:

x = 35

\=x = 42.1

SD = 6.6

Female Athletes

x = 54

\=x = 34.3

SD = 10.1

Required

Determine which athlete had more extreme age

To do this, we simply calculate the standard z score using

z = \frac{x - \=x}{SD}

For the actor:

z = \frac{35 - 42.1}{6.6}

z = \frac{-7.1}{6.6}

z = 1.0758

For the actress:

z = \frac{54 - 34.3}{10.1}

z = \frac{19.7}{10.1}

z = 1.950

Comparing both z values;

The actress has the more extreme age because

  • <em>It has a positive z value</em>
  • <em>Its z value is greater than that of the actor</em>

<em></em>

The value of x from the given expression is 5/6

<h3>Expansion of equation</h3>

Given the expression to expand expressed as:

15 = 3/5(6x + 20)

We are to determine the value of x

15(5) = 3(6x + 20)

Expand

75 = 18x +60

Collect like terms

18x = 75 - 60

18x = 15

x = 15/18

x = 5/6

Hence the value of x from the given expression is 5/6
