State if the scenario involves a permutation or a combination. Then find the number of possibilities. The student body of 215 students wants to elect two representatives.

Permutation/Combination:

David must install fencing around a lot that is shaped like a right angle.the side of lot that runs east-west is 200 ft long.the side of the lot runs north-south is 125 ft long.calculate how many feet of fencing he will need to surround the entire lot.

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

Me with geometry ! in this figure, bc is a perpendicular bisects of kj. dm is the angle bisects of bdj. what is the measure of bdm? •60° •90° •30° •45°
