Answers:
1. gh = -21
2. g^2 - h = 46
3. g + h^2 = 2
4. g + h = -4
5. h - g = 10
6. g - h = -10
Step-by-step explanation:
1. -7 x 3 = -21
2. -7^2 = - 49
-49 + 3 = -46
3. 3^2 = 9
-7 + 9 = 2
4. -7 + 3 = -4
5. 3 - -7 = 3 + 7 = 10
6. -7 - 3 = -10

Each team needs two people for a 3-legged race.
Therefore, the number of orders (combinations) of 2 people at a time from 8 is
