Answer:

1320, permutation

Step-by-step explanation:

There are 12 members

Pick a president

We have 12 choices

Now there are 11 people left to pick from

now pick a vp

We have 11 choices

Now there are 10 people left to pick from

now pick a secretary

We have 10 choices

12*11*10 = 1320

This is a permutation since it matters who is president, vp and secretary

Factorise fully 3x-9x^2

artcher [175]

Answer:

$3x(1 - 3x)$

Step-by-step explanation:

We can factor the expression by using the common factor.

Pull out 3x from the expression.

$3x - 9 {x}^{2} \\ 3x(1 - 3x)$

Common Factor is similar to dividing by the term we pull out. When we pull out the term, we divide the whole expression and keep the term out of the expression.
