If x2 + 12x + n is a perfect square trinomial, then n =?
2 answers:
Answer:
36
Step-by-step explanation:
There is a pattern. Try expanding some binomials to see the pattern.
Compare that last line with the problem.
<em>n</em> is the square of <u>half</u> the coefficient of <em>x</em>. In the two examples given above,
9 is the square of half of 6
25 is the square of half of 10
The square of half of 12 is

<h2>Answer:</h2>
There are 1757600 possibilities.
<h2>Step-by-step explanation:</h2>In a certain state, fishing licenses are in the form of LLL NN
L stands for a letter of the alphabet (a to z)
N stands for a one-digit number from 0 to 9.
Now, for the series LLL, 3 alphabets are placed that can be any from a to z. This means at each place, 26 letters can be placed.
Similarly, for NN, 2 numbers are placed that can be any, between 0 and 9. At each place 0 to 9 can be placed.
Hence, the total possible outcomes will be :
=1757600
Therefore the answer is 1757600 possibilities.
