Answer:
3) 18 , 4) 25/3
Step-by-step explanation:
for 3
since the shapes are similar to ratio between 3 and 6 is the same as between 9 and x
since 6 was 2 times more than 3, x would be 2x more than 9 - thus the answer is 18
for 4
the shapes are similar so the ratio between 6 and 5 is the same as between 10 and x, since the ratio from 6 to 5 is 5/6 you multiply 10 by 5/6 to get
50/6 -> 25/3
thus the answer is 25/3
