Given:
CDEF is dilated by a scale factor of  to form the quadrilateral C'D'E'F'.
 to form the quadrilateral C'D'E'F'.
To find:
The measure of side E'F'.
Solution:
If a figure is dilated by a scale factor of k, then the side of dilated figure is k times of corresponding side of original figure.
CDEF is dilated by a scale factor of  to form the quadrilateral C'D'E'F'. So,
 to form the quadrilateral C'D'E'F'. So,

From the given figure it is clear that  . So,
. So,


Therefore, the measure of side E'F' is 9 units.
 
        
             
        
        
        
The answer is going to be
x= 2,0
y= 0, -6
        
             
        
        
        
Add 5 to both sides to get x alone and you will have your answer which is x= -3
 
        
                    
             
        
        
        
Answer:
x=11
Step-by-step explanation:
(7x+14)=(9x-8)
7x-9x=-14-8
-2x=-22
-2x/-2=-22/-2
x=11
