Answer:
-N
Step-by-step explanation:
Given expressions are:
-(-N)
-N
|N|
|-N|
To find: Which of the given expressions are not equal to N.
Solution:
Let us consider and solve each expression one by one:
-(-N)
Negative of negative becomes positive.
In the given expression, same thing is done so negative of negative gives us a positive result.
-(-N) is equal to N
-N
Negative of N can not be equal to N.
|N|
First of all, let us learn about modulus / absolute function.
Absolute function always gives us positive result even if there is a negative sign inside the expression.
So, |N| is equal to N.
|-N|
As explained above, result from modulus/absolute function comes out to be positive.
So, |-N| is equal to N.
Hence, the answer is -N.

Answer:
A, C, and E are correct.
Step-by-step explanation:
B is incorrect because a line that passes through point F would be the bisect, not line segment AB
D is incorrect because it just is.
Answer:
51.8
Step-by-step explanation:
Multiply 15 by z and -51 which would equal (15z-765).
Add 765 to 12 and that equals 777
Divide 777 by 15 which would equal 51.8
Let, the integers = x,(x+1)
x*(x+1) = 56
x²+x = 56
x²+x-56 = 0
x²+8x-7x-56=0
x(x+8)-7(x+8)=0
x+8= 0 OR x-7=0
x = -8 OR x = 7
it would be -8 & -7 or 7 & 8
