BRAINLIEST! I NEED 3 and 4

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

i believe the answer is letter c) 8

step-by-step explanation:

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
