x (x cubed + 2) (3 x minus 7)
x (3 x Superscript 4 Baseline minus 7 x cubed + 6 x minus 14)
Answer:
x(x³ + 2)(3x - 7)
Step-by-step explanation:
I got it right
The solution is Option D.
The equation is simplified as A = x ( 3x⁴ - 7x³ + 6x - 14 )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
A = 3x⁵ - 7x⁴ + 6x² - 14x be equation (1)
Now , on factorizing the equation , we get
Taking the common factor as x in the equation , we get
A = x ( 3x⁴ - 7x³ + 6x - 14 )
Therefore , the value of A is x ( 3x⁴ - 7x³ + 6x - 14 )
Hence , the equation is A = x ( 3x⁴ - 7x³ + 6x - 14 )

mia has 14 coins in her pocket that total $1.10. what are the coins in her pocket
Answer: Either 8 dimes and 6 nickles, or 4 quarters and 10 pennies. Both combinations add up to $1.10.
Have a nice day
The 14 coins can be:
- 8 dimes and 6 nickels
Or
- 10 pennies and 4 quarters
Given,
14 coins make up $1.10
We need to find what are the 14 coins.
What are the different types of coins that make up a dollar?We have,
100 pennies = $1
20 nickels = $1
10 dimes = $1
4 quarters = $1
Find the coins that are worth $1.10
We have
10 dimes = $1
So,
1 dime = $0.10
8 dimes = $0.80 _____(1)
20 nickels = $1
So,
1 nickels = $0.05
6 nickels = $0.30 _____(2)
100 pennies = $1
10 pennies = $0.1 _____(3)
4 quarters = $1 ______(4)
From (1) and (2)
8 dimes + 6 nickels = $0.80 + $0.30
14 coins = $1.10
From (3) and (4)
10 pennies + 4 quarters = $0.1 + $1
14 coins = $1.10
Thus the 14 coins can be:
- 8 dimes and 6 nickels
- 10 pennies and 4 quarters

A manufacturer who is considering the implementation of a one-week training program for all new employees decides to test the program with the next 100 employees hired, and then compare their productivity rate to the productivity rate of new employees based on past records–a rate that is normally distributed with a mean of 60 and a standard deviation of 8. The new program needs to produce a minimum improvement of 4 to be considered worthwhile. What is the comparison distribution's standard deviation?
Answer:
0.8
Step-by-step explanation:
From the given information:
The population mean = 60
The standard deviation = 8
The sample size = 100
The sample distribution which follows a normal distribution is the set of values taken by this statistic on each sample from the same population.
The standard deviation of the comparison distribution's = [tex]\dfrac{\sigma}{\sqrt{n}}[/tex]
The standard deviation of the comparison distribution's = [tex]\dfrac{8}{\sqrt{100}}[/tex]
The standard deviation of the comparison distribution's = 8/10
The standard deviation of the comparison distribution's = 0.8

Carla wants to know how many batches of birdseed she can make with 1/2 cup of sunflower seeds. She puts 1/6 cup of sunflower seeds in every batch. Carla divides 1/2 by 1/6 to find the answer. She says this is the same as multiplying 1/6 by 2; explain what Carla did wrong and show the correct solution.
Answer:
she was wrong because when you divide 1/2 by 1/6 its not the same as multiplying 1/6 by 2 but you do get the same answer its just the wrong equation
Step-by-step explanation:

Answer:
Carla inverted the numerator when she should have inverted the denominator before multiplying3Step-by-step explanation:
Any division problem is the same as a multiplication problem with the multiplier being the reciprocal of the denominator. So to divide 1/2 by 1/6, we could multiply 1/2 by (1/(1/6)) = 6/1. The result would be ...
[tex]\dfrac{1}{2}\div\dfrac{1}{6}=\dfrac{1}{2}\times\dfrac{6}{1}=\dfrac{6}{2}=\boxed{3}[/tex]

Carla's mistake was inverting 1/2 instead of 1/6 in her solution to the problem.

The difference is just decimal places
Evaluating the two values, both numbers 9.90 and 9.9 are equal.
The value 9.90 is written to 2 decimal places as the value of 0 in the hundredth place adds no value in terms of size to the number. The other value 9.9 is written to 1 decimal place. Hence, both values are of equal size.Hence, the values 9.90 and 9.9 are equal.

Solve for x
8x+12=4x−16
Answer:
X= -7
Step-by-step explanation:
When you get X to one side and simplify you get -7
8x + 12 = 4 x - 16
Subtract 12 from both sides
8x = 4x - 28
Subtract 4x from both sides
4x = -28
Divide both sides by 4 to get rid of the coefficient so we know what x alone is equal to, instead of what we have currently which shows what 4 x's equals
x = -28/4
x = -7
Understanding the answer1x = - 7
One x is equal to - 7 units.

The area of the top face of a cube is 16 square inches. Use 8 of these cubes to make a rectangular
prism. What is the volume of the rectangular prism? Hint: The shape of each face of a cube is a
square.
Answer:
The volume of the rectangular prism is 512 inches³
Step-by-step explanation:
Any cube has 6 square faces
Area of any square = L × L, where L is a length of each side
The volume of the cube = L × L × L
∵ The area of the top face of a cube = 16 inches²
→ Find which number multiply by itself = 16
∵ 16 = L × L
∵ 16 = 4 × 4
∴ L = 4 inches
Let us find the volume of 1 cube
∵ The volume of the cube = L × L × L
∵ L = 4 inches
∴ The volume of each cube = 4 × 4 × 4
∴ The volume of each cube = 64 inches³
∵ We will use 8 of this cube to make a rectangular prism
→ That means the volume of the rectangular prism is 8 times
the volume of 1 cube
∴ The volume of the prism = 8 × volume of 1 cube
∵ The volume of each cube = 64 inches³
∴ The volume of the prism = 8 × 64
∴ The volume of the prism = 512 inches³
The volume of the rectangular prism is 512 inches³

A cell phone plan costs $30 per month for unlimited calling plus $10 per GB of data used. If Alejandro can only afford for his cell phone bill to be $60 a month, how many GB’s can he use in a month, maximum? Your answer will be a whole number. *
1 point
Answer:
3 GB
Step-by-step explanation:
If the cell phone plan cost $30 per month
then subtracting this amount from $60 we have
$60 - $30 = $30
it 1 GB costs $10
therefore dividing this amount with $30
we have
$30/$10 = 3
Alejandro can only afford 3GB per month.

–2x(1–3x) + (2x + 3)(3x – 2)
Answer: 4x² + x - 2
Step-by-step explanation: First distribute the -2x into (1-3x) which = -2x + 6x²
Now let's work on the second part:
Distributing (2x + 3) to (3x - 2) = 6x² - 4x + 9x - 6. Combining like terms: 6x² - 4x + 9x - 6 --> 6x² + 5x - 6. Now let's combine the like factors of our two equations which equals
12x² + 3x - 6. Now reduce by dividing by 3 which gives us the final answer of:
4x² + x - 2.
