Assume a class has 17 members.
Helga [31]
A) 4080
B) 6188

A is a permutation, since order would matter:
P(17, 3)=\frac{17!}{(17-3)!}=\frac{17!}{14!}=4080

B is a combination, since order does not matter:
_{17}C_5=\frac{17!}{5!12!}=6188

I think u guys know what to do !!!
kotykmax [81]

Answer:

B, C

Step-by-step explanation:

7 - x = 18

A.

7 - 2x = 18 - x

126 - 14x = 324 - 18x

We are nowhere near the solution.

B.

-x = 11

x = -11

This works.

C.

7 = x + 18

-11 = x

This works.

D.

25 - x = 36

-25 + x = -36

This does not help.

E.

7 = x + 18

0 = x + 11

We still do not have a solution.

Answer: B, C
