Answer:
[tex]36n^2+12n+1[/tex]
Step-by-step explanation:
Foil the equation!
1. You see that is to the second power so it means this [tex](6n+1)*(6n+1)[/tex]
2. Then you use the Foil method. First, Outside, Inside, and Last.
3. Combined like terms
4. Answer!
A tip you can use to avoid Foil is this mental math trick: (Keep in mind this only works if the polynomial is being squared.)
1. Multiply the first number by itself = [tex]6n *6n = 36n^2[/tex]
2. Add the first number by itself = [tex]6n+6n = 12n[/tex]
3. Multiply the last number by itself = [tex]1*1 =1[/tex]
4. Combined to form your answer = [tex]36n^2+12n+1[/tex]
NOTE: This is the same thing as a foil but it uses mental math so it takes less time!

To find the sum of interior angles of this polygon you have to use the equation
S=180(n-2)
where n is the number of sides
S=180(6-2)
S=180(4)
S=720 degrees
The sum of all angles is 720 degrees
[tex]110 + x + 25 + x - 30 + x + x + 115 = 720[/tex]
[tex]4x = 720 - 110 - 25 - 115 + 30[/tex]

The total volume of water in the pool =-2 (x-11)(x+5) ft^3
Step-by-step explanation:
a) (2x^2 + 12x + 10) - (4x^2-100)
= 2x^2+12x+10-4x^2+100
= -2x^2+12x+110
b)
Lets simplify first by taking the GCF out:
= -2 (x^2-6x-55)
Now Just simplify by finding the product of a and c
I used -11 and 5 because when you multiply -11x5 you get -55, and when you do -11+5 you get -6.
= -2 (x-11)(x+5) ft^3
Answer:
Given expressions

The Income-tax Sasha has to pay is $2334
What is Income Tax?
The part of income a person pays to the government as a contribution to the growth of the nation is called Income Tax.
Sasha earns $16 per hour
Total hours she worked is 2000
Total annual income is $16 *2000 = $32000
Deductions = $12550
Net Salary = $32000 - $12550
Salary on which tax has to be paid = $19450
According to the federal law, Tax table 2021
For income in the range of $9,951 to $40,525 the tax will be 12%
12% of $19450 has to be paid
=(12/100) * 19450
=$2334
Therefore, the Income tax Sasha has to pay is $2334

You are considering selling your home. You consult with an agent who gives you the asking prices of five homes (comps) in your area: $165,000, $188,000, $175,000, $150,000 and $400,000. The $400,000 is an outlier so you will not include it in your evaluation. In determining a reasonable asking price, what is the mean of the four remaining comps?
Answers
Answer:
$169,500Step-by-step explanation:
Mean is the average of the numbers. It is expressed as the ratio of the sum of the numbers to its sample size.
Mean = sum of the amounts/sample size
Sum of the amounts = $165,000 + $188,000 + $175,000+$150,000
Sum of amounts = $678,000
Sample size = 4 (excluding the outlier)
Mean = $678,000/4
Mean = $169,500
Hence the mean of the four remaining comps is $169,500
hi can someone help me with my question, which is 2 ( 3 + x) - 7 = x + 5?
Answers
Answer: x=6
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
2*(3+x)-7-(x+5)=0
(2 • (x + 3) - 7) - (x + 5) = 0
x - 6 = 0
Solve : x-6 = 0
Add 6 to both sides of the equation :
x = 6
Answer:
x = 6
Step-by-step explanation:
2(3+x)-7=x+5
We move all terms to the left:
2(3+x)-7-(x+5)=0
We add all the numbers together, and all the variables
2(x+3)-(x+5)-7=0
We multiply parentheses
2x-(x+5)+6-7=0
We get rid of parentheses
2x-x-5+6-7=0
We add all the numbers together, and all the variables
x-6=0
We move all terms containing x to the left, all other terms to the right

Surgical treatment of a broken arm costs $16,911. You have a $1,000 deductible and then your insurance will pay 85% of the remaining cost. Your insurance also has an out-of-pocket maximum charge of $3,500. What is your cost?
Answers
Using proportions, it is found that your cost is of $12,411.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, the treatment costs $16,911, with a deductible of $1,000, hence the price is already of $15,911.
The insurance will pay 85% of the remaining cost, or $3,500, whichever is greater, hence:
0.85 x 15911 = $13,524 > $3,500.
Hence, the insurance pays only $3,500, and your cost is given by:
15911 - 3500 = $12,411.

Step-by-step explanation:
This is because the line segment VX, reaches from one end of the circle to the other, touch both sides of the circle. The other options do not make sense since segment XY does not go through the center of the circle and TX is the radius of the circle. The radius is half the diameter of the circle.
Therefore, the answer is VX.

Which of the following number lines and solution sets show the values of r that make the inequality -2r+3<9 true
Answers
Answer:
"Solving'' an inequality means finding all of its solutions. A "solution'' of an inequality is a number which when substituted for the variable makes the inequality a true statement. When we substitute 8 for x, the inequality becomes 8-2 > 5. Thus, x=8 is a solution of the inequality.
Step-by-step explanation:
Example 1:
Consider the inequality
displaymath173
The basic strategy for inequalities and equations is the same: isolate x on one side, and put the "other stuff" on the other side. Following this strategy, let's move +5 to the right side. We accomplish this by subtracting 5 on both sides (Rule 1) to obtain
displaymath174
after simplification we obtain
displaymath175
Once we divide by +2 on both sides (Rule 3a), we have succeeded in isolating x on the left:
displaymath176
or simplified,
displaymath177
All real numbers less than 1 solve the inequality. We say that the "set of solutions'' of the inequality consists of all real numbers less than 1. In interval notation, the set of solutions is the interval tex2html_wrap_inline187 .
Example 2:
Find all solutions of the inequality
displaymath189
Let's start by moving the ``5'' to the right side by subtracting 5 on both sides (Rule 1):
displaymath190
or simplified,
displaymath191
How do we get rid of the ``-'' sign in front of x? Just multiply by (-1) on both sides (Rule 3b), changing " tex2html_wrap_inline201 " to " tex2html_wrap_inline203 " along the way:
displaymath192
or simplified
displaymath193
All real numbers greater than or equal to -1 satisfy the inequality. The set of solutions of the inequality is the interval tex2html_wrap_inline205 .
Example 3:
Solve the inequality
displaymath207
Let us simplify first:
displaymath208
There is more than one route to proceed; let's take this one: subtract 2x on both sides (Rule 1).
displaymath209
and simplify:
displaymath210
Next, subtract 9 on both sides (Rule 1):
displaymath211
simplify to obtain
displaymath212
Then, divide by 4 (Rule 3a):
displaymath213
and simplify again:
displaymath214
It looks nicer, if we switch sides (Rule 2).
displaymath215
In interval notation, the set of solutions looks like this: tex2html_wrap_inline227 .

The ordered pairs in the table lie in the graph of the linear function whose equation is
y = 3x + 2.
Which ordered pair does not lie on the graph of this function?
A. (10, 32)
B. (8, 13)
C. (–5, –13)
D. (–8, –22)
Answers
Answer:
b
Step-by-step explanation:
Hi ok heres how I got it:
If the equation is y=3x+2, we just need to plug in each x and y value and see which one doesn't work. Either that, or we can just locate it on the graph.
For example,
10,32
Plugging it in gives us:
32=3(10)+2.
This is correct, meaning that A is NOT the answer.
Continuing testing, and we will find that B is the incorrect pair.
13=3(8)+2 is NOT correct.
13=24 is not equal.
Also,
-13=3(-5)+2 CORRECT,
-22=3(-8)+2 CORRECT AS WELL
Answer:
The ordered pair does not lie on the graph of this function is B. (8, 13)
Step-by-step explanation:
=> y = 3x + 2...i)
By putting the value of x in equation i).. from the options
firstly, putting the value of x = 10
=> y = 3(10)+2
=> y = 32
so, its the ordered pair that lie on the graph
now , putting the value of x= 8
=> y = 3(8) +2
=> y = 24 +2
=> y = 26
its 26, so the ordered pair does not lie on the graph of this function is B. (8, 13)

1990s = 22 months of very hot weather
What is the percent increase in hot weather months from the
1980s to the 1990s?
Percent increase = (22 months - 5 months) / 5 months × 100
