Answer» Option D is correct answer d is a right answere plz like thoko n!/(n-5)! divided by (n!/(n-3)!) = 2/1 n!/(n-5)! * (n-3)! / n! = 2n! cancel (n-3)! / (n-5)! = 2 Expand (n-3)! (n-3)(n-4)(n-5)! / (n-5)! = 2 (n-5)! cancel (n-3)(n-4) = 2n^2 - 7n + 12 = 2n^2 - 7n + 10= 2(n-5)(n-2) = 0n = 5 or n = 2, but we need n to be 5 or greater, son = 5

Answer»

Option D is correct answer

d is a right answere plz like thoko

n!/(n-5)! divided by (n!/(n-3)!) = 2/1

n!/(n-5)! * (n-3)! / n! = 2n! cancel

(n-3)! / (n-5)! = 2

Expand (n-3)!

(n-3)(n-4)(n-5)! / (n-5)! = 2

(n-5)! cancel

(n-3)(n-4) = 2n^2 - 7n + 12 = 2n^2 - 7n + 10= 2(n-5)(n-2) = 0n = 5 or n = 2, but we need n to be 5 or greater, son = 5
