Answer: 12v² + 18v
Step-by-step explanation:
Given
6v (2v + 3)
Apply distributive property by multiplying 6v to both 2v and 3
= 6v · 2v + 6v · 3
= 12v² + 18v

Step-by-step explanation:
1) As U is the mid point of TV ,it divides the whole line in two equal parts:
TV=TU+UV
TU=UV
Subtitute values:
5x+6=23+23
5x+6=46
5x=46-6
5x=40
x=40/5
x=8
2) Q is mid point of PR so PQ=QR
PR=PQ+QR
15x-29=6x-1+6x-1
15x-29=12x-2
15x-12x=29-2
3x=27
x=27/3
x=9

Answer For Number 4: The distance between the two points is five.
Step-by-step explanation:
First outline the triangle, draw lines connecting the two points and form a right angle triangle. Use the graph to count the distance between point A and point B ( the one at the bottom point A, and the one towards the top point B ). Sorry, Imma stop explaining this because I suck at wording, I’ll show how to solve with picture.
Can you please answer this?

how many numbers are there between 256 and 789 that are divisible by 7
Answer:
76
Step-by-step explanation:
How many numbers are between 256 and 789 are divisible by 7 ?
Generalizing, we could look for a procedure that, given two integers A and B, with B>A , and a module M, tells us how many integers x, with A<=x<=B , are divisible by M.
a) let n1 be the lowest integer >=A such that n1 is divisible by M.
If n1>B , than not even n1 has the required properties and the output of the procedure is 0; otherwise, go to the next step.
n1 will be the first number of the sequence of numbers divisible by M.
b) let n2 be the highest integer <=B such that n2 is divisible by M.
Notice that it’s not possibile that n2<A , as you alway have the possibility n2=n1 .
n2 w
A simple way to think about this is by calculating the largest multiple of 7 less than 256 (let’s call it y) and the smallest multiple of 7 greater than 789 (let’s call it x). The answer is then all the multiples of 7 in between these two numbers, which can be represented by:
x−y7−1
Let’s do it:
252 is the largest number less than 256 divisible by 7. y = 252
791 is the smallest number greater than 789 that’s divisible by 7.
Thus, our answer is 113-36–1 = 76.
Note: we subtract 1 or else we would include the number on the top end of the range (in this case, 791).
Hope it helped you!!

Is the following rational or irrational?
Square root 16
Square root 12
12/5
0.36274959282619
Answer:
rational
irrational
rational
rational
Step-by-step explanation:
Square root 16 = 4 rational since it can be written as a fraction of integers
Square root 12 = 2 * sqrt(3) irrational since sqrt(3) is irrational
12/5 rational since it is a fraction of integers
0.36274959282619 rational since it is a terminating decimal

Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle C?
Enter your answer in the box.
Answer:
C = 80
Step-by-step explanation:
A cyclic quadrilateral is one where all 4 vertices touch the circumference of a circle.
It has 1 interesting property that should concern you: <B + <D = 180 degrees.
3x - 59 + 2x - 1 = 180 Combine like terms
5x - 60 = 180 Add 60 to both sides.
5x = 180 + 60
5x = 240
x = 240/5
x = 48
Now go to 2x + 4.
x = 48
A = 2*48 + 4
A = 96 + 4
A = 100
So C = 180 - 100
C = 80
What letter stays the same when reflected over the x-axis
When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.p explanation:

What is the GCF of 48&72
Answer:
24 is GCF
Step-by-step explanation:
48 = 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
72 = 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Factors they have in common: 1, 2, 3, 4, 6, 8, 12, 24
24 is the greatest factor they have in common; therefore, 24 is the greatest common factor, or GCF

I need help ASAP pls
Answer:
[ no solution ]
Step-by-step explanation:
[tex]3x - 2 = 9x + 10 - 6x[/tex]
group x terms together and constants together:
[tex]3x - 9x + 6x = 10 + 2[/tex]
factorise out x on the left hand side :
[tex] x(3 - 9 + 6) = 12 \\ x(0) = 12[/tex]
since coefficient of x is 0, there is no solution.

- Judy wrote a check for $63, then made a deposit
of $ 110. What was the overall chang to her
Account.
Answer:
$47
Step-by-step explanation:
110-63=47
Answer:
+$47
Step-by-step explanation:
As you are calculating for change, assume that the bank account has $0.
Judy wrote a check for $63, or she withdrew $63:
0 - 63 = -63.
Next, she deposited $110, or she added $110:
-63 + 110 = 47
The over all change to her account is a net profit of +$47.

-5n-4(-7-4n)=36+7n
What is N?
Answer:
n=2
Step-by-step explanation:
-5n-4(-7-4n)=36+7n
Distribute
-5n +28 +16n = 36+7n
Combine like terms
11n +28 = 36+7n
Subtract 7n from each side
11n+28-7n = 36+7n-7n
4n+28 = 36
Subtract 28 from each side
4n+28-28 = 36-28
4n = 8
Divide by 4
4n/4 = 8/2

the temperature for the first 4 days in january was -2 degrees
the mean temperature for the first 5 days in january was 0 degrees
what was temperature on the 5th day ?
URGENT
let's assume the temperature on 5th day be x
We know that :
[tex] \boxed{mean = \frac{sum \: \: of \: all \: \: observations}{number \: \: of \: \: observations} }[/tex]
So,
[tex] \hookrightarrow \: 0 = \dfrac{ - 2 + ( - 2) + ( - 2) + ( - 2) + x}{5} [/tex]
[tex] \hookrightarrow \: 0 \times 5= - 2 - 2 - 2 - 2 + x[/tex]
[tex] \hookrightarrow \: 0 = - 8 + x[/tex]
[tex] \hookrightarrow \: x = 8[/tex]
Therefore, temperature on the fifth day was x = 8
