There are 12 people on the swim team. How many ways can the coach select 3 people to swim in the relay?

There are 12 choices for the first person, 11 for the second and 10 for the third so the answer is 12 * 11 * 10 = 1320.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
