The number of permutations of the 25 letters taken 2 at a time (with repetitions) is:25^{2}
The number of permutations of the 9 digits taken 4 at a time (with repetitions) is:
9^{4}
Each permutation of letters can be taken with each permutation of digits, therefore the total number of possible passwords is:
25^{2}\times 9^{4}=4,100,625

How to Find x value: 9-0.75(x+8)-5=-6.5
Dahasolnce [82]
Here's how to find the value of x:

<span>9 - 0.75 ( x + 8 ) - 5 = -6.5      find the difference of 9 - 0.75

</span><span>8.25 ( x + 8 ) - 5 = -6.5           add 5 to both sides
</span>
8.25 ( x + 8 ) = -1.5                distribute 8.25 to x and 8

8.25x + 66 = -1.5                    subtract 66 from both sides

8.25x = -67.5                          divide both sides by 8.25

x = 18.18181818......            the value of x is 18 2/11

hope this helps
