Simplify (x − 4)(x2+ 5x + 2). x3 + x2 − 18x − 8 x3 + x2 + 22x − 8 x3 + 9x2 − 18x − 8 x3 + 9x2 + 22x − 8

Answers

Answer:

{x}^(3)  +  {x}^(2)  - 18x - 8

Step-by-step explanation:

The given expression is:

(x - 4)( {x}^(2)  + 5x + 2)

We need to expand using the distributive property:

x( {x}^(2)  + 5x + 2) - 4( {x}^(2)  + 5x + 2)

This implies that:

{x}^(3)  + 5 {x}^(2)  + 2x - 4 {x}^(2)  - 20x - 8

Regroup similar terms and simplify:

{x}^(3)  +  {x}^(2)  - 18x - 8

The first choice is correct.

Answer:  A) x³ + x² - 18x - 8

Step-by-step explanation:

  (x - 4)(x² + 5x + 2)

= x(x² + 5x + 2) - 4(x² + 5x + 2)

=   x³  + 5x² + 2x - 4x² - 20x - 8

=   x³ + (5x² - 4x²) + (2x - 20x) - 8

=  x³  +       x²        +     -18x      - 8

Joey's cleaning service charges $50 per week to clean a home. Amy's cleaning service charges $50 per week , plus $25 for cleaning supplies.which equation can be used to express the amount that Amy's cleaning service charges?

A y=50x

B y=50x-25

C y=1/50x

D y=50x + 25

Answers

Answer:

D y=50x + 25

Step-by-step explanation:

The number of weeks can vary, so it is placed in front of a variable. The cleaning supplies cost does not, so it does not have a variable, but instead, it is a constant.

Answer:

D

Step-by-step explanation:

y = mx + b is the equation, where m = cost per week and b = cleaning supply cost (constant)

That means the equation is y = 50x + 25

If a normal distribution has a mean of 104 and a standard deviation of 4 what is the z score for a value of 110

Answers

The z-score for 110 is 1.5

Step-by-step explanation:

Let us define z-score first

A z-score for a given value is the relationship of the value to the mean.

It tells us that how many standard deviations, a value is close or far from the mean. Let the value be x

The formula for calculating z-score is:

z-score = (x-μ)/σ

Given

Mean = μ = 104

SD = σ = 4

Putting the values in the formula

z = (110-104)/4

=6/4

=3/2 = 1.5

The z-score for 110 is 1.5
