12a−a
=12a−1a
=12a+−1a
=a+a+a+a+a+a+a+a+a+a+a+a+−a
=a+a+a+a+a+a+a+a+a+a+a
=11a
Answer:
Step-by-step explanation:
We have to make 5 place serial number with first two as alphabets and last three as digits.
The alphabets are bonded to first 6 ( A, B, C, D, E, F) where as digits are 10 (say 1 to 10).
Let the serial number be S1 S2 S3 S4 S5.
For Alphabets
For S1 we have 6 alphabets.
Now for S2 we are left with 5 alphabets since there is no repetition one alphabet will be fix for S1.
So the possible combination for S1 S2= 6x5=30.
For Digits
We did the same as we did for alphabets, for S3 we have 10 possibilities, and for S4 and S5 9 and 8 respectively due to the no repetition condition.
So the possible combinations for S3 S4 S5 = 10x9x8=720
So the total number of serial numbers are 30+720=750.

Formula for volume of a cuboid 
. where l is the length, w is the width and h is the height.
Using this equation we can answer the question by using the values given.
From the list of answers, we can compare each one to the answer we got and see if they match up.
The answers that match up are:
C. 
- it is exactly like the answer we got.
D. 
- if we simplify the brackets, it is exactly like the answer we got.
E. 
- once again, if we simplify the brackets it is like the answer we got.
None of the other answers are correct as they do not match up with the answer we got.
