Prime numbers have only 2 factors 1 and its number for example:
2, 3, 5, 7, 11, 13, 17, 19, 23
Like this 1*2. Or 3*1
Composite numbers have more than two factors for example :
0, 4, 6, 8, 9, 10, 12, 14 15, 16..
For example 0 has many factors
0 times 3 0times 4
Answer:
1) 15
2) 10
3) 11
4) -4
5) -8
6) 12
7) 14
8) -6
Step-by-step explanation:
Substitute the values thats all lol, if u need a more detailed explanation just comment <3
Answer:
C. x + 9 = 11
Step-by-step explanation:
We are trying to identify which of the equations does not match with the others. In this case, solve for x in each equation:
Option A):
6 + x = 9
Subtract 6 from both sides:
6 (-6) + x = 9 (-6)
x = 9 - 6
x = 3
Option B):
15 = x + 12
Subtract 12 from both sides:
15 (-12) = x + 12 (-12)
15 - 12 = x
x = 3
Option C):
x + 9 = 11
Subtract 9 from both sides:
x + 9 (-9) = 11 (-9)
x = 11 - 9
x = 2
Option D):
7 + x = 10
Subtract 7 from both sides:
x + 7 (-7) = 10 (-7)
x = 10 - 7
x = 3
---------------------------------------------------------------------------------------------------------
As you can tell, all the equations end with x = 3 as there answers except C. x+9=11, making (C) your answer.

Answer:
See below:
Step-by-step explanation:
So we know that there is a 
feet long board and that it is split into 6 pieces.
With that information, we can split it by doing the following:
1. 
We can do this because we have a board that is 0.75 feet long and we multiply it by one sixth because we want to divide a fraction and to do that we have to flip the fraction.
After doing that, we get our answer of 
This means that each piece is 
feet long.
Cheers!
