<h3>Combination</h3>This a mathematical technique that is used to determine the number of possible arrangements in a collection of items where the way they're arranged does not matter.
Data;
- Number of Students = 12
- Team = 5
The combination for this would be

Answer:
9 cm, 7 cm, 6 cm and 8 cm
Step-by-step explanation:
The perimeter is the sum of all the sides.
4 sides' expressions are given, so we add them and equate to 30.
Note: we disregard the value of x = -6, because it is going to give us side with negative length, that can't happen!
So, we take x = 4
Hence, length of each side is:
x + 5 = 4 + 5 = 9 cm
x + 3 = 4 + 3 = 7 cm
2x -2 = 2(4) - 2 = 8 - 2 = 6 cm
x^2 - 2x = (4)^2 - 2(4) = 16 - 8 = 8 cm
These are the lengths of 4 sides: 9 cm, 7 cm, 6 cm and 8 cm.
