Answer:
Step-by-step explanation:
Let's start by making up as many teams as we can with the 32 student. Given that each team is different, we can make 10 teams of 3 each. (we still have 23 more teams to make).
The last two people make a team of only 2. No matter which student from the 30 other students is picked, the team of two and the one the student is coming from will have one student in common. Though there are more borrowings that take place (many more), the results remain as stated. At least 2 teams will have 1 person in common.
The method is called the pigeon hole method.

Step-by-step explanation:
Find what both expressions have in common
V=Bh so you would do 25.4 x 17 which equals 431.8
Answer:
x=75
Step-by-step explanation:
∆FSJ~∆DYJ
so the sides are proportional
SJ/YJ=FJ/DJ
(63+42)/42=(x+50)/50
105/42 ×50=x+50
125-50=x
x=75
