Answer:
Step-by-step explanation:
Goven the length of the field = 110m
Width = 80m
The length of the diagonal is expressed using the pythagoras theorem;
d² = l² + w²
d² = 110² + 80²
d² = 12100 + 6400
d² = 18500
d = √18500
d = 136.01
Hence the players have to run 136.01m diagonally
The answer is 9, here are all the possible combinations...
road, road
road, bridge
road, ferry
bridge, bridge
bridge, ferry
bridge, road
ferry, ferry
ferry, bridge
ferry, boat
(or you can do 3 input combinations by 3 output combinations "3 x 3" = 9)
Cheers!
Answer:

Step-by-step explanation:
1. take out constants
( 5 × 2 × 4 × - 4 × - 2) 
2. simplify 5 × 2 to 10
(10 × 4 - 4 × - 2)
3. simplify 10 × 4 to 40
(40 × - 4 × - 2)
4. simplify 40 × -4 to -160
(-160 × - 2)
5. simplify -160 × -2 to 320

6. use product rule:

7. simplify 5 + 5 to 10

8. simplify 10 + 5 to 15
