Answer:
Option E
Step-by-step explanation:
if 
0, let us plugging different value for n
if n=1
2n = 2 x 1 = 2>n
but if n=-1
2n= 2 x -1 = -2<n
So I is not always true
Now, for the same value of n, let us check the other two statements
= 
= 1 which is not greater than n
So II is also not true
2 - n = 2 - 1 = 1 which is not greater than n
So we can see that none of the statement is true,
So the correct answer is option E
Answer:
x = 6
Step-by-step explanation:
Given
3x - 11 = - 2x + 19 ( add 2x to both sides )
5x - 11 = 19 ( add 11 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Answer:
C
There are an even amount of sides on each object.

Answer:
The length is 16.1 ft and the width is 4.7 ft
Step-by-step explanation:
Let
x -----> the total length of the tables
y -----> the width of the tables
we know that
The area is equal to
so
-----> equation A
-----> equation B
substitute equation B in equation A
Solve the quadratic equation by graphing
The solution is 
Find the value of x
therefore
The length is 16.1 ft and the width is 4.7 ft
