A. We are given that the combination is 1 letter and 8
digits, so the total number of unique combinations would be the product of each
possibilities.
Total unique ID’s = 26 * 10 * 10 * 10 * 10 * 10 * 10 * 10
* 10
or can also be written as
Total unique ID’s = 26 * 10^8
Solving:
Total unique ID’s = 2.6 x 10^9
B. Let us now calculate the total unique ID’s if there is
only 1 letter followed by 3 digits.
Total unique ID’s = 26 * 10^3
Total unique ID’s = 26,000
Since there are 48,000 students and only 26,000 unique ID’s,
therefore it is not enough.

Answer:
the correct answer is B :) can i have brainly?
Step-by-step explanation:
Multiply both sides by 3 to cancel out the 3 in the denominator of the left side of the equal sign. You get:
x + 4 = 18
Now subtract 4 from both sides to get variables one side, constants on the other.
x = 18 - 4
x = 14
Your answer is x = 14
Step-by-step explanation:
A trinomial is an expression that has three terms.
Square trinomial
A square trinomial is simply a perfect square trinomial, and it is represented as:
\mathbf{a^2 + 2ab + b^2 = (a + b)^2}a2+2ab+b2=(a+b)2
Difference of square binomials
This is easily identified because, the terms of the square binomials are perfect squares.
The difference of square binomials is represented as:
\mathbf{a^2 - b^2 = (a + b)(a - b)}a2−b2=(a+b)(a−b)
Sums and difference of cubes
When cubes are added or subtracted, they can be expressed using the following
\mathbf{a^3 + b^3 = (a + b)(a^2 - ab + b^2)}a3+b3=(a+b)(a2−ab+b2) --- sum of cubes
\mathbf{a^3 - b^3 = (a - b)(a^2 + ab + b^2)}a3−b3=(a−b)(a2+ab+b2) --- difference of cubes
