Line segments can be divided into sub-segments.
The value of DF is 18
The given parameters are:
[tex]\mathbf{BE = 3x + 6}[/tex]
[tex]\mathbf{DF = 7x + 4}[/tex]
We have:
[tex]\mathbf{BE + DF = 30}[/tex]
So, we have:
[tex]\mathbf{3x + 6 + 7x + 4 = 30}[/tex]
[tex]\mathbf{10x + 10 = 30}[/tex]
Subtract 10 from both sides
[tex]\mathbf{10x = 20}[/tex]
Divide both sides by 10
[tex]\mathbf{x = 2}[/tex]
Substitute [tex]\mathbf{x = 2}[/tex] in [tex]\mathbf{DF = 7x + 4}[/tex]
[tex]\mathbf{DF = 7 \time 2 + 4}[/tex]
[tex]\mathbf{DF = 14 + 4}[/tex]
[tex]\mathbf{DF = 18}[/tex]
Hence, the value of DF is 18

Show that 3650 is not a perfect square.
Answer:
A number that is a perfect square never ends in 2, 3, 7 or 8. If your number ends in any of those numbers, you can stop here because your number is not a perfect square. Obtain the digital root of the number. The digital root essentially is the sum of all of the digits.

77^1/10 can be written as [tex]\sqrt[10]{77}[/tex]
what is representation of root?The principal nth root of a is written as n√a , where n is a positive integer greater than or equal to 2. In the radical expression, n is called the index of the radical.
A radical symbol √ is used to represent a square root; the number or expression included within the radical symbol, designated by the letter a below, is known as the radicand.
We have that [tex]77 ^ {1/10}[/tex].
Now, if we have given that √4 we can write it as [tex]\sqrt[2]{4}[/tex]
Again, if we have [tex]7^{1/3}[/tex] we can write it as [tex]\sqrt[3]{7}[/tex]
Similarly we can write 77^1/10 as [tex]\sqrt[10]{77}[/tex]

The sum of three consecutive odd integers is 237.what are the integers
Answer:
let the 1st number be x
then second number is x+2
then third number is x+2+2
according to question
sum of three consecutive odd integers is 237.
hence, x+x+2+x+2+2=237
3x+6=237
3x=237-6
3x=231
x=231/3
x=77
therefore 1st integer is 77
2nd integer is 77+2=79
3rd integer is 77+2+2=81
Answer:
77, 79, 81
Step-by-step explanation:
You can represent the equation as follows:
x + x + 2 + x + 4 =237
Combine like terms.
3x + 6 = 237
Subtract 6 from both sides.
3x = 231
Divide both sides by 3.
x = 77
Now, add 2 to 77 to determine the second integer.
77 + 2 = 79
Add 4 to 77 to determine the third integer.
77 + 4 = 81

You move left 6 units. You end at (-4, 4). Where did you start?
(you need a coordinate plane)
Answer:
(2,4)
Step-by-step explanation:
Step 1: Understand the question
We know moving left DECREASES the x value and moving right INCREASES the x value.
We need to move 6 units back to the right to get the original coordinate
Step 2: Solve
(-4 + 6, 4)
(2, 4)
Step 3: Therefore statement
Therefore you started at (2, 4)
HELP ASAP! Pls and thx! Need help.
Answer:
y = -3x + 22
Step-by-step explanation:
To find m, find the change in y and divide it by the change in x.
For example, the change in y between 19 and 13 is -6. Then determine the change in x. For example, since we determined the change in 19 and 13, let's look at the change in the x coordinates that pair with 19 and 13: 1 and 3. The change in x between 1 and 3 is 2. Now divide the change in y by the change in x: -6/2 = -3. So now we have the equation y = -3x + b, but we still need to figure out b, or the y-intercept. To do this, we need to figure out a pattern in the table to find out what y is equal to when x = 0, the definition of a y-intercept. From just the table alone, it looks like for every 2 units the x-coordinate decreases, the y-coordinates increases by 6. We could also just as easily say that for every 1 unit the x-coordinate decreases, the y-coordinate increases by 3. From this definition, if we look at the coordinate (1, 19), if we were to decrease 1 from the x-coordinate, we would have to increase the y-coordinate by 3 which we can write as (x - 1, y + 3). So, we would get (0, 22). So, when x = 0, y = 22.

Hence, the value of z is -39/7.
