How many ways are there to rearrange the letters ALIVE in such a way that the word EVIL is not contained in the resulting word
Sergio [31]

Answer: 118 combinations.

Step-by-step explanation:

In ALIVE we have 5 letters, rearranging it we have the possible options of:

5 options for the first letter.

4 options for the second letter, as one was already chosen for the first one

3 options for the third letter, as 2 were already chosen.

2 options for the fourth letter.

1 option for the last letter.

The total number of combinations will be equal to the product of the numbers of options for each letter, then we have:

5*4*3*2*1 = 120 combinations.

And the combinations where the word EVIL is formed are:

AEVIL

EVILA

2 combinations, then the total number of combinations such that the word evil is not formed are:

120 - 2 = 118 combinations.

Solve following | 2x + 9 = 15
vivado [14]
  • Answer:

<em>x₁ = 3</em>

<em>x₂ = - 12</em>

  • Step-by-step explanation:

<em>Hi there ! </em>

<em>| 2x + 9 | = 15</em>

<em>1.</em>

<em>2x + 9 = 15</em>

<em>2x = 15 - 9</em>

<em>2x = 6</em>

<em>x = 6 : 2</em>

<em>x₁ = 3</em>

<em>2.</em>

<em>2x + 9 = - 15</em>

<em>2x = - 15 - 9</em>

<em>2x = - 24</em>

<em>x = - 24 : 2</em>

<em>x₂ = - 12</em>

<em>Good luck ! </em>
