Answer:
Option D (8,4)
Step-by-step explanation:
we know that
The dilation centered at the origin  (0,0) is very simple. To find out the image point multiply the scale factor to the x  and  y-coordinates of the pre-image point.
so
(2*4,2*2) -----> (8,4)
 
        
             
        
        
        
Answer:
1 | 38
2 | 76
3 | 114
5 | 190
1/2 | 19
2/3 | 25.33
Step-by-step explanation:
I am assuming that you need to multiply the area by the scale factors

I don’t understand what your asking. there is no numbers involved or a equation.
        
             
        
        
        
To multiple fractions, you multiply numerator x numerator, then denominator x denominator. in this example, first convert 1 1/2 to an improper fraction. it will become 3/2. for this equation, you next multiply. so, (7x3)/(8x2). this simplified to 21 over 16. Anna's mistake is that she multiplied 7 x 1/2 rather than 7/8 x 1 1/12
