Answer:
[tex]-a^2+ab[/tex]
Step-by-step explanation:
So the sentence can be written like this:
[tex]((a^2-b^2)+(a^2+ab+3b^2))-((a^2-2ab+b^2)+(2a^2+2ab+b^2))[/tex]
Now you can combine like terms in the first part of the equation and the second part:
[tex]((a^2+a^2)+ab+(-b^2+3b^2))-((a^2+2a^2)+(-2ab+2ab)+(b^2+b^2))[/tex]
Which leaves you with:
[tex](2a^2+ab+2b^2)-(3a^2+2b^2)[/tex]
Now distribute the negative to the second part of the equation:
[tex]2a^2 + ab + 2b^2-3a^2-2b^2[/tex]
Combine like terms again:
[tex](2a^2-3a^2)+ab+(2b^2-2b^2)[/tex]
Which becomes:
[tex]-a^2+ab[/tex]
Answer:
- a² + ab
Step-by-step explanation:
summing the first 2 expressions
a² - 2ab + b² + 2a² + 2ab + b² ← collect like terms
= 3a² + 2b² → (1)
summing the next 2 expressions
a² - b² + a² + ab + 3b² ← collect like terms
= 2a² + ab + 2b² → (2)
Subtracting (1) from (2)
2a² + ab + 2b² - (3a² + 2b²) ← distribute parenthesis by - 1
= 2a² + ab + 2b² - 3a² - 2b² ← collect like terms
= - a² + ab

There are 120 people in a school canteen.
Half of the people in the canteen are in year 11 students.
The number of year 11 students in the canteen is three times the number of year 10 students.
The rest of the people in the canteen are year 9 students.
the number of year 9 students : the number of year 10 students = n : 1
Work out the value of n.
You must show how you get your answer.
2:1
Step-by-step explanation:
List all variables
Total people=120
year 11 students=120/2=60
year 10 students=60/3=20
subtract year 10 and 11 students from the total to get the number of year 9 students
year 9 students=120-60-20
=40
year9:year10
40:20
2:1
Value of variable 'n' as per the given condition number of 9 year students : number of 10 year students = n:1 is equals to 2.
What is variable?" A variable is defined as the quantity which represents the change in value as per the given condition in a mathematical problem."
According to the question,
Total number of students in school = 120
As per the conditions given we have,
Number of 11 year students = [tex]\frac{120}{2}[/tex]
= 60 people
Number of 11year students = 3 × ( Number of 10 year students)
⇒Number of 10 year students = [tex]\frac{Number of 11 year students}{3}[/tex]
= [tex]\frac{60}{3}[/tex]
= 20 people
Number of (11year + 10year + 9year ) students = 120
⇒ 60 + 20 + Number of 9 year students =120
⇒Number of 9 year students = 120 - 80
= 40 people
Substitute the value in the given condition to get the value of the variable we get,
Number of 9 year students : Number of 10 year students = n:1
⇒40 : 20 = n: 1
⇒n = 2
Hence, value of variable 'n' as per the given condition number of 9 year students : number of 10 year students = n:1 is equals to 2.

How am I supposed to solve this math problem that Edmentum gave me?
“Dear Dr. Jones,
Our pharmaceutical company now received 47 complaints about the new pain reliever NoPain, created in your lab. Of the 47 complaints, 24 said their headache got worse, 15 said they had severe cramping after taking the medication, and 8 said they had both problems. We have only been distributing this pain reliever for about 30 days and we are very concerned. It has cost our company roughly 1.2 million dollars to create the drug and we have recorded sales of $98,600 in the past month at $10 a bottle, so that is 9,860 bottles. Should we be concerned? Do you think we should pull the product and conduct more research? We may end up losing money on this if we pursue this course of action. Should we keep the product on the shelves and secretly do more research? Or should we just do nothing for the time being, wait it out, and see what happens? Please get back to us as soon as possible with your recommendation.
Thank you,

A bag holding 7 1/5 pounds of mixed nuts will be divided equally among 9 people.
How many pounds of nuts will each person get?
Answer:
4/5
Step-by-step explanation:
So sorry if im wrong <3
Answer:
Each person will get 4/5, or 0.8 pounds of nuts.
Step-by-step explanation:
First, we need to convert 7 1/5 into an improper fraction, by multiplying
7 x 5 = 35
and adding
35 + 1 = 36
Our improper fraction is 36/5
Now, we can divide
36 / 9
5 / 1
To do so, we need to switch 9/1 to its reciprocal, 1/9, and then multiply
36 x 1 = 36
5 x 9 = 45
Our answer is 36/45
We can simplify our answer by dividing by 9
36 / 9 = 4
45 / 9 = 5
Our final answer is 4/5, or 0.8 pounds of nuts

The sun is about 390 times farther than earth is from the moon
Step-by-step explanation:
It's kind of hard to understand the question but it's essentially asking how many times farther earth is from the sun than earth is from the Moon. Or basically measure the distance from the earth to the moon. Then show how much bigger the distance from the Earth to the Sun is by comparing it from the earth to the moon. To do this you divide the distance of moon by the distance of the sun to get how many times you could you could fit the distance between the Earth and The Moon from the Earth to the Sun.
Help please. I dont know how to do this :((
Answer:
You need the distance of all four sides so that is:

Communitive property of addition is a number plus a number and the number added to the first number backwards but equal the same answer. For instance (if you don't understand what I'm saying) Look at answer A in your problem, a+b=b+a that's how the communitive property works in addition. The rest of the answer choices also shows communitive property. This is why answer D does NOT show the communitive property in addition.

if 3 chickens in 3 days layed 3 eggs how many eggs would be layed by 12 chickens in 12 days
Answer:
142
Step-by-step explanation:
(if I'm doing the math in my head right)3×3×3 to find the number of eggs that three chickens would lay in three days, so that would be 27it seems like it's saying that chickens can only lay 3 eggs per day, so what I would do is multiply 12*12 (144) and then multiply 144 by 3so maybe 142?What is the measure of an angle of a regular polygon with nine sides?
Answer:
140 degrees
Step-by-step explanation:
To find the value of an internal angle within this polygon, we can just multiply the number of triangles by 180 ° , then divide by the number of internal angles, which is nine. Excellent! So the interior angle of a 9 -sided polygon is 140 ° .

What is the leading coefficient of a third degree function that has an output of 221 when x=2, and has zeros of −15, 3i, and −3i?
Answer:
1
Step-by-step explanation:
The function with the given zeros will factor as ...
f(x) = a(x +15)(x^2 +9) . . . . with leading coefficient 'a'
You have ...
f(2) = 221 = a(2+15)(2^2+9) = a(17)(13) = 221a
Then a = 221/221 = 1
The leading coefficient is 1.
_____
Additional comment
As you know, a function with zero x=p has a factor of (x -p). The given zeros mean the function has factors (x -(-15)), (x -3i). and (x -(-3i)). The product of the last two factors is the difference of squares: (x^2 -(3i)^2) = (x^2 -(-9)) = (x^2 +9). This is how we arrived at the factorization shown above.
