Answer:

The final expression should be 4x-1

Step-by-step explanation:

The error occurs in the simplification from the 3rd to 4th step. You can see two positive 2x's, but suddenly they vanish.

4 + 2x - 5 + 2x

4 - 5 + 4x

-1 + 4x

4x -1

Eight committee members are meeting in a room that has twelve chairs. In how many ways can they sit in the chairs
amm1812

Answer:

<h2>495 different ways</h2>

Step-by-step explanation:

We will use the combination rule to solve this questions since it bothers selection. Combination has to do with selection.

If r objects are to be selected from n pool of objects, this can be done in nCr number of ways.

nCr = n!/(n-r)!r!

If there are Eight committee members meeting in a room that has twelve chairs, the number of ways they can sit in the chair can be done in 12C8 number of ways.

12C8 = 12!/(12-8)!8!

12C8 = 12!/4!8!

12C8 = 12*11*10*9*8!/4*3*2*8!

12C8 =  12*11*10*9/4*3*2

12C8 = 11*10*9/2

12C8 = 11*5*9

12C8 = 495

<em>Hence the committee can sit in the chairs in 495 different ways</em>
