Answer:
₂₁C₉ = 293930
Step-by-step explanation:
9 members out of 21 senators will be selected on the subcommittee on Economy Policy
So we are in case of combinations of 21 people in groups of 9
₂₁C₉ =21! /( (21-9)!) *9! ⇒21*20*19*18*17*16+15*14*13*12! /(21-9)! *9!
=21*20*19*18*17*16*15*14*13/ 9! ⇒ = 19*2*17*15*14*13/6 ⇒ =293930
The greatest common factor of 9, 18 and 21 is 3 so that is the number that we'll factor out
to do this divide all three numbers by 3 to get
3(3a-6b+7c)
I hope I've helped!
1. (1*100,000,000)+(1*10,000,000)+(9*1,000,000)+(9*10)+(3*1)= (expanded form) 2. one hundred nineteen million ninety three. ( worded form)
