5 0

Answer:

The simplified expression is:

\frac{2(u + 7)}{(u- 2)}

Step-by-step explanation:

We want to simplify:

\frac{2 {u}^{2}  - 20u + 42}{ {u}^{2}  - 5u + 6}

We factor the numerator and the denominator to get:

\frac{2(u - 3)(u + 7)}{(u- 2)(u- 3)}

Cancel out u-2 which is common to the numerator and the denominator yo get:

\frac{2(u + 7)}{(u- 2)}

An art gallery curator wants to select four paintings
jasenka [17]

255 different groups of 4 paints can be selected out of the 20 paintings.

<h3>How many groups of four paintings can be chosen?</h3>

If we have a set of N elements, the number of groups of different sets of K elements that we can make out of these N is given by:

C(N, K) = N!/(K!*(N - K)!)

In this case we have a total of 20 paintings, and the curator wants to select 4, then we have:

N = 20

K = 4

The number of different combinations of 4 paintings is given by

C(20, 4) = 20!/(4!*16!) = (20*19*18*17)/(4*3*2*1) = 255

This means that 255 different groups of 4 paints can be selected out of the 20 paintings.
