Let's start by identify a 30-60-90 triangle
If we compare those two traingles we can stablish the following relation:
![\begin{gathered} a\sqrt[]{3}=6\sqrt[]{3} \\ \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a%5Csqrt%5B%5D%7B3%7D%3D6%5Csqrt%5B%5D%7B3%7D%20%5C%5C%20%20%5Cend%7Bgathered%7D)
Therefore, a=6
u is the opposite side to the 90° angle, therefore

on the other hand, v is the opposite side to the 30° angles, so
Alright so I'm coming up with this on the fly; you have the first six letters (a,b,c,d,e,f) and 0-9 and your ten numbers. calculate the amount of possible combinations for the letters by simply writing them down.
ab, ac, ad, ae, a f- five
bc, bd , be, bf- four
cd, ce, cf- three
de, df- two
ef,- one.
adding these all together gets a total of 15 for the letters. now the numbers
01, 02, 03, 04, 05, 06, 07, 08, 09- nine
12, 13, 14, 15, 16, 17, 18, 19- eight
23, 24, 25, 26, 27, 28, 29- seven
34, 35, 36, 37, 38, 39- six
45, 46, 47, 48, 49- five
56, 57, 58, 59- four
67, 68, 69- three
78, 79- two
89- one
added together with a total of 45 combinations.
alright so, 45 different number combinations and 15 letter combinations. multiplying 15 by 45 should tell you the total possible combinations for a two letter and two number serial-number

Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given the function

Put x =-4 in given function
Bedmas
so basically 6 + 4 x 3 - 2
6+ 12 - 2
18 -2
16 is the answer
