Answer:

<h2>20 {x}^{3}  - 36 {x}^{2}  + 7x +  3</h2>

Solution,

(5x + 1)(2x - 1)(2x - 3)

= 5x(2x - 1) + 1(2x - 1) \times (2x - 3)   \\  = (10 {x}^{2}  - 5x + 2x - 1)(2x - 3) \\  = (10 {x}^{2}  - 3x - 1)(2 x - 3) \\  = 10 {x}^{2} (2x - 3) - 3x(2 x - 3) - 1(2x - 3) \\  = 20 {x}^{3}  - 30 {x}^{2}  - 6 {x }^{2}  + 9x - 2x + 3 \\  = 20 {x}^{3}  - 36 {x}^{2}  + 7x + 3

Hope this helps..

Good luck on your assignment...

Seven x's and 3y's cost as much as 4z's. One z costs as much as 1x plus 1y together. How many x's cost as much as 1y?
Pie

Answer:

Step-by-step explanation:

Equations

7x + 3y = 4z

<em>Second equation</em>

x + y = z                          Multiply the entire equation by 4

4[x + y = z]                      Now distribute the 4 through the equation

4x + 4y = 4z                    Both equations = 4z. Equate the lefts.

<em>Third equation   </em>

7x+3y = 4x + 4y              Subtract 3y from both sides

7x + 3y -3y = 4x + 4y -3y

7x = y + 4x                      Subtract 4x from both sides

7x - 4x = y + 4x - 4x       Combine

3x = y

Answer: 3x = y

Solve for x
Ghella [55]

Answer:

1. x=105

2. 12 cans for $4

3. 14

Step-by-step explanation:

1. 15/18 = x/126

126/18=7

x=15*7=105

2. 12 cans for $4.  36 for $11.50.  

36/3=12.  11.50/3=3.8333.  

12 cans for $4 is the better deal because it would be an equal deal if it was 36 for 12:00.  

3. Circumference = pi*d.  Circumference = 43.96.  pi=3.14.  3.14*x=43.96.  x=diameter.  x=14.  diameter = 14

--Explanation to 3.14*x=43.96:

3.14*x=43.96, = 3.14x=43.96

3.14x*100 =43.96*100

314x=4396

314x/314 = 4396/314

x=14

A real estate company would like to see if the average sale price of townhouses in a particular school district has changed in t
Dennis_Churaev [7]

Answer:

Step-by-step explanation:

a) We would set up the hypothesis test.

For the null hypothesis,

H:0 µ = 280000

For the alternative hypothesis,

H1: µ ≠ 280000

This is a 2 tailed test

Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is

z = (x - µ)/(σ/√n)

Where

x = sample mean

µ = population mean

σ = population standard deviation

n = number of samples

From the information given,

µ = 280000

x = 294365

σ = 22898

n = 36

z = (294365 - 280000)/(22898/√36) = 3.76

b) Since α = 0.05, the critical value is determined from the normal distribution table.

For the left, α/2 = 0.05/2 = 0.025

The z score for an area to the left of 0.025 is - 1.96

For the right, α/2 = 1 - 0.025 = 0.975

The z score for an area to the right of 0.975 is 1.96

In order to reject the null hypothesis, the test statistic must be smaller than - 1.96 or greater than 1.96

Therefore, the rejection regions are area to the left of - 1.96 and to the right of 1.96 on the normal distribution curve.

The calculated test statistic is 3.76 for the right tail and - 3.76 for the left tail

c) Since - 3.76 < - 1.96 and 3.76 > 1.96, we would reject the null hypothesis.
