Just plug in the the values for a, b, and c into the expression.
1/7(16/-4+8(3-√25)^2)
1/7(-4+32)
1/7(28)

Answer: 1/3
Step-by-step explanation:
We know that after dilation with scale factor k the coordinates of pre-image (x,y) map to (kx,ky) of the image.
From the given graph, the coordinate of A =(9,4) and the coordinate of A' (3,2)
Then 
 and 

Therefore, the scale factor of the dilation is 1/3.
 
        
             
        
        
        
Answer: 5
Step-by-step explanation:
The LCM for the denominators 5 and 1 is 5. So that means the LCD is 5.
3/5 = 3/5 x 1/1 = 3/5
27 = 27/1 x 5/5 = 135/5
