What is the scale factor in the dilation?

5) 4cm x 4cm = 16cm; then 16 / 2 = 8 to get the triangle on top

    answer- 24cm

6) 6m x 2m = 12m; 8m x 2m = 16m; then add it together

   answer- 28m

7) 9 x 8 = 72; 4 x 2 = 8 (this will equal the little triangles); 72-8

   answer- 64ft

8) 5 x 12 = 60 - 24

  answer- 36in

9) (4 x 4) + (6 x 8)

  answer- 64ft

hope this helps :D
