Answer:
4 n (2) + 10 n +4
Step-by-step explanation:
Step-by-step explanation:
Simplify the expression by opening parenthesis:
(4n + 5)² - 9 =(4n)² + 2*5*(4n) + 25 - 9 =4(4n²) + 4(10n) + 4(4) =4(4n² + 10n + 4)As we see the expression has 4 as one of factors so is divisible by 4.

What is the slope between (-3, 8) and (4,8).
Help please now :)
Answer:
0
Step-by-step explanation:
There are 2 ways to find slope. Slope is rise over run, meaning that it is the change in y over change in x. The first way is to use the formula. The formula is as follows [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. Plug the coordinates into the equation and then simplify. This ends up looking like [tex]\frac{8-8}{4+3}[/tex] or [tex]\frac{0}{7}[/tex]. So the slope is just 0 because anything divided by 0 is 0. You could also get the answer of 0 by realizing that this is horizontal. All horizontal lines have a slope of 0.

the number of ducks and pigs in a field = 38. the total number of legs among them is 92. each duck has 2 legs and each pig has 4 legs, how many ducks and how many pigs?
9514 1404 393
Answer:
30 ducks8 pigsStep-by-step explanation:
Let p represent the number of pigs. Then the number of ducks is 38-p and the number of legs is ...
4p +2(38 -p) = 92
2p = 16 . . . . . . . . . . . . collect terms, subtract 76
p = 8 . . . . . . 8 pigs in the field
38-p = 30 . . . number of ducks in the field
There are 30 ducks and 8 pigs in the field.

He pays a total of $55.48.
He pays a total of $3.48 for the cookies.
He buys 8 bags of onions that each cost the same amount.
Write and solve an equation which can be used to determine xx, how much each bag of onions costs.
Answer:
$6.5Step-by-step explanation:
Given:
Total cost = $55.48Cookies = $3.48Onions = 8 bags for x eachEquation:
8x + 3.48 = 55.488x = 55.48 - 3.488x = 52x = 52/8x = 6.5Each bag of onions costs $6.5
The ratio of two similar rectangles is 5:2, and the area of the larger on is 400 ft^2. What is the area of the smaller rectangle?
Answer:
400/5*2=160 ft^2
Step-by-step explanation:
Times the common multiple of 3 and 6, which is 6
The larger rectangle takes up 5 parts and the smaller one takes up 2 parts, so 400/5 is the area of one part, times 2

given that l is parallel to m find the measure of angle QTP
Answer:
m<QTP= 45.5º
Step-by-step explanation:
180-89=91
since it is parallel ÷2
91÷2=45.5
Answer:
<QTP = 43 degrees
Step-by-step explanation:
5x - 32 = 3x (corresponding angles)
5x - 3x = 32
2x = 32
x = 32/2
x = 16
5x - 32 = 5(16)-32 = 48
< QTU = 89 (corresponding angles)
180- 89 - 48 = <QTP
43 degrees
y raise to power 1/2 =3
Answer:
y = root 9
Step-by-step explanation:
1/2 is equivalent to the root of something.
The root of y equals 3.
Therefore, y would be equal to root 9, as root 9 is equivalent to 3.
Hope this helps :)
y^1/2 = 3
√y = 3
Raise both sides to power 2
( √y )^2 = ( 3 )^2
y = 9

A bottle contains liters of soda. Henry has 12 of these bottles.
How much soda does he have in all?
Write your answer in simplest form.
The question that should be given:-
A bottle contains 12 litres of soda. Henry has 12 of these bottles. How much soda does he have in all? Write your answer in simplest form.
Solution :-
• 1 bottle contains 12 litres of soda
• Total number of bottles = 12
To calculate how much soda does Henry have in total l, we need to multiply the number of bottles and the number of litres in each bottle. So,
[tex]total \: soda = (12 \times 12)litres[/tex]
[tex]→144 \: litres[/tex]
Therefore, the total soda that Henry has in all is 144 litres
--------------------- ★ -----------------------
{ Note:- Even if it was any other number, then just multiply the given number of litres of soda into the total number of given bottles.
This means that,
Total Soda = Given litres of soda x Total bottles given
Ex:- Total bottles given is 2 bottles
and given number of litres in one bottle is 8, so, multiply 8 x 2 = 16.
This means that total number of litres is 16 litres. }
Given above is an example. Please do misunderstand it with the answer.

An arts academy requires there to be 6 teachers for every 144 students and 5 tutors for every 40 students. How many students does the academy have per teacher? Per tutor? How many tutors does the academy need if it has 72 students
Answer:
3 teachers and 9 tutors
Step-by-step explanation:
Answer:
There are 24 students per teacher and 8 students per tutor. If the academy has 72 students, then 9 tutors would be needed.
Step-by-step explanation:
We will start with the question, how many students does the academy have per teacher. To find this, we need to set up the equation. 144 will be the number of students, 6 will be the number of teachers, and x will be the number of students per teacher.
144/6=x
24=x
So, there are 24 students for every teacher.
We could also do this as a ratio. We would do the same thing. We would divide by six to get our answer.
144:6
Make the six one.
24:1
This shows that there are 24 students for every teacher.
Now to find out how many per tutor.
We will do the same thing as before, minus the ratio, though you could still use the ratio. Remember, 40 is the number of students, 5 is the number of tutors, and x is the number of students per tutor.
40\5=x
8=x
So there are 8 students per tutor.
Now we will use this knowledge to solve for how many tutors are needed if the academy has 72 students.
We will set up our equation. 72 will be the students, we will use eight since that is how many students are needed per tutor, and x will be the number of tutors needed.
72/8=x
9=x
So this means that if the academy has 72 students, then it will need 9 tutors.

Answer:
In short your answer is Options 2, 3 and 4.
Step-by-step explanation:
Option 1:
If you distribute 4 among everything in the parenthesis, you'll get 4 × x = 4x and
4 × 4 = 16. Essentially your answer will be
4x + 16, so this is not equivalent.
Option 2:
If you combine like terms 2x and 2x, you'll get 4x, then add 3 and 1 to get 4. Your answer will be 4x + 4. So this is equivalent.
Option 3:
If you distribute 2 among everything in the parenthesis, you'll get 2 × 2x = 4x and 2 × 2 = 4. Essentially your answer will be 4x + 4, so this is equivalent.
Option 4:
If you combine like terms 3x and x, you'll get 4x. So essentially your answer is
4x + 4, so this is equivalent.
Hope this helped :)

A thread was folded in half, and then it was folded again, forming a bundle. Then the thread was cut into pieces by a striaght cut through the enitre bundle. Ine of the pieces is 8 cm, and the longest piece is 18 cm. What is the longest possible length of the thread
The longest possible length of the thread is;
Length = 144 cm
Let the length of the thread be x cm.
Now, it is first folded in half. This means divided into 2. Thus, we now have length as x/2.
We are told it is folded again. This means the length after second folding is now; (x/2) ÷ 2 = x/4.We are told that there is now a straight cut through the entire bundle with one of the pieces being 8cm and the longer piece being 18 cm.This means the ratio is; 8:18
Since the new length after the final folding is x/4, then it means after cutting;longer length will be; [tex](\frac{18}{8 + 18})[/tex] [tex]* (\frac{x}{4})[/tex]
Thus, we now have;
18 = (18/26) × (x/4)
18 will cancel out to give; x = 26 × 4
x = 144 cm
Therefore the longest possible length of the thread = 144 cm

Huilan is 5 years older than Thomas. The sum of their ages is 57. What is Thomas's age?
Answer:
21
Step-by-step explanation:
You can write this question out with two separate formulas, the first one being H - 5 = T, and the second being H + T = 57. I am using the variables of H and T to show the ages of Hulian and Thomas respectively. From here, we can use the substitution formula since we already know what T is equal to (H - 5). Substituting the equation in, we get a new equation of H + (H + 5) = 57. Subtracting 5 from both sides gives us the equation of H + H = 52, or 2H = 52. Dividing by 2 yields the answer of 26 for Hulian's age. Since we know that Hulian is 5 years older than Thomas, we can subtract 5 from 26, giving us Thomas' age, which is 21.
Answer:
23.5
Step-by-step explanation:

If x - 15 = 7 - 5(x - 4). Then what does x equal?

x-15=7-5(x-4)
x-15=7-5x+20
+5x +5x
6x-15=7+20
+15 +15
6x=7+20+15

x=7
9514 1404 393
Answer:
x = 7
Step-by-step explanation:
Eliminate parentheses and collect terms. Then solve the resulting 3-step linear equation.
x -15 = 7 -5x +20
x -15 = -5x +27
6x -15 = 27 . . . . . . step 1, add 5x to put the variable term on one side
6x = 42 . . . . . . . . . step 2, add 15 to put the constant term on the other side
x = 7 . . . . . . . . . . . . step 3, divide by the coefficient of the variable
_____
Additional comment
The variable terms have coefficients 1 and -5. We choose to add the opposite of the term with the least coefficient (farthest left on the number line). That way, the variable term ends up with a positive coefficient.
