Answer:

Step-by-step explanation:
9 raised to 2 is
=> 
=> 9 * 9
=> 81
To solve this polynomial equation, we first factor the left side.
To factor x² + 8x + 12 = 0, look for factors of 12 that add to 8.
These factors are 6 and 2 so we have (x + 6)(x + 2) = 0.
So either x + 6 = 0 or x + 2 = 0 and solving for
x in each equation, our answer is {-6, -2}.

Probability = 0.0556
Step-by-step explanation:
We have 9 different letters, so the total number of words we can make is:

If we want just the words that begin with L and end with a vowel, we would have the first letter "locked", so we have 8 letters remaining, and it must end with a vowel, so the last "slot" has just 4 possible values (A, E, I or O). Then we would have 4 possible values for the last letter and 7 remaining letters in the middle of the word:

The probability is calculated by the division of the number of words we want over the total number of words:
