1) 40
2)9x-12
3)42
Step-by-step explanation:
1) A square has 4 sides, and if one side's length is 10, the perimeter (distance around the square) is 10 times 4=40
2) Simply add these values together to get 9x-12
3) Plug in 6 as x in 9x-12. (6*9)-12=54-12=42
Answer:
5 jumps
Step-by-step explanation:

3 fall to 2 - 5 fall to 4 - 7 fall to 6 - 10 fall to 9 - 12.
