N order to write an expression like (5x + 4)3 in expanded form, it helps to look at (5x + 4) as just one number, n.

Vladimir79 [104]

The expression (5x + 4)^3 in expanded form is 125 x3 + 300 x2 + 240 x + 64. The expression will have also a root of x = -4/5. This is the form of trinomial expansion and can be solve by multiplying the the term 3 times.

You must select a team from a group of 6 boys and 10 girls. How many ways can you select 2 boys and 5 girls?

Keith_Richards [23]

Using the combination formula, it is found that you can select 2 boys and 5 girls in 2,520 ways.

In this problem, Joao and Elisa would be the same team as Elisa and Joao, hence the order is not important and the <em>combination formula</em> is used to solve this question.

<h3>What is the combination formula?</h3>

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by:

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem:

2 boys are selected from a set of 6.

5 girls are selected from a set of 10.

Hence:

$T = C_{5,2}C_{10,5} = \frac{5!}{3!2!} \times \frac{10!}{5!5!} = 2520$

You can select 2 boys and 5 girls in 2,520 ways.
