Triangle A is the original triangle, and triangle A' is the image.
We need a pair of corresponding sides in the two triangles that are both labeled with lengths.
We see the side labeled 15.2 mm in triangle A', and we see the side labeled 3.8 mm in triangle A. These two sides are corresponding sides.
Divide the length of the side in the image by the length of the side in the original to find the scale factor.
(15.2 mm)/(3.8 mm) = 4
The scale factor is 4.
The answer will be 9 1/12 because if you add them up you get 11/12. So the mixed number would be 9 1/12
D) 8.17 x 10^8
910000000 - 93000000 = 817000000
817000000 ---> 8.17 x 10^8
135 miles / 3 hours = 45 mph
Ok this is a hard problem of math you need to count the numbers form one through 100 and through 10 or 20 but keep it in oder
