Use distributive law to factor the given expression: 3+21a+15b

Reil [10]

Answer:

$3(1+7a+5b)$

Step-by-step explanation:

The distributive law states that

$a\cdot (b+c)=a\cdot b+a\cdot c.$

The expression 3+21a+15b consists of three terms:

3=3·1;
21a=3·7a;
15b=3·5b.

You can see that 3 is the common factor of these three terms, thus

$3+21a+15b=3(1+7a+5b).$

A disc jockey wants to select 4 songs from a new cd that contains 12 songs. How many ways can the disc jockey choose four songs?

WARRIOR [948]

I suppose a DJ wants to select 4 different songs, then there are: 12*11*10*9 = 11880 ways to choose them.

If the order of the songs he plays doesn't matter, there are: $\frac{12 * 11 * 10 *9 }{4!} = 495$ ways to choose them.
