Answer:
3
Step-by-step explanation:
<u>1) Find two corresponding lengths between the image and the pre-image</u>
Pre-image (bottom side) = 3 units
Image (bottom side) = 9 units
We can use any corresponding lengths for this step.
<u>2) Divide the length of the side from the image by the length of the side from the pre-image</u>
9 units ÷ 3 units
= 3
Therefore, the scale factor of the dilation is 3.
I hope this helps!
 
        
                    
             
        
        
        
Answer:
Whole numbers are positive numbers (this includes 0) that do not have decimals or fractions to them. 
Example:
1, 2, 3, 4, 5,etc are all whole numbers, because they are positive and do not have decimals or fractions
1.25 would not be a whole number, because although it is positive, it has a decimal.
