Answer:
C
Step-by-step explanation:
Given Coordinates:
(-4, -2), (2, -2), (4, 2), (-2, 2)
The shape that uses the coordinates (-4, -2), (2, -2), (4, 2), (-2, 2) would make a parallelogram.
See graph for answer:
So correct choice is C.
 
        
                    
             
        
        
        
The answer for your problem is shown on the picture.
 
        
             
        
        
        

So, Option C is correct.
Step-by-step explanation:
We need to find Volume of cone.
We are given:
π = 3.14
Length = 27 cm
Diameter = 15 cm
The formula used to find Volume of cone is:

We are given diameter but we need radius in the formula
So, Radius = Diameter/2 = 15/2 = 7.5 cm
We need to find height of cone.
Using Pythagoras theorem:

So, Height of cone = p= 25.93
So, r= 7.5 and h= 25.93 and π = 3.14
Putting values in the formula:


Rounding off to the nearest tenth:

So, Option C is correct.

Substitute 2x+1 where y is in the equation:
9x-2(2x+1)=8
Then distribute the -2(2x+1)
9x-4x+2=8
Then combine like terms (the x)
5x+2=8
Then do -2 on both side of the equation sign
5x+2=8
 - 2 -2
Then you'd get
5x=6
Then divide 5 on both sides 
X= 1.2
