Step-by-step explanation:
11
C
4
We use formula n! /((n-r)!r!)
11!/((11-4)!4!)
11!/((7!)(4!))
11x10x9x8x7!/(7!)(4!)
11x10x9x8/(4!)
11x10x72/24
11x10x3
330
Therefore number of ways =330
Answer:

Step-by-step explanation:
8 + 6 + 7.2 = 14 + 7.2 = 21.2
3a + 2ab - 6 + 2b - ab
First, gather like terms. / Your problem should look like: (3a - 6a) + (2ab - ab) + 2b
Second, simplify. / Your problem should look like: -3a + ab + 2b
Answer: -3a + ab + 2b
