The librarian could use 3 and 18 as a factor pair
<h3>How to determine the factor pair</h3>
The number of books is given as:
n = 54
Express 54 as a product of two numbers
54 = (1, 54), (2, 27),(3, 18) and (6, 9).
From the options, we have the following factor pair
3 and 18
Hence, the librarian could use 3 and 18 as a factor pair

Answer:
14 squares
Step-by-step explanation:
1. We know if the mosaic is a square shape, all sides are the same length and consist of the same amount of squares
2. Area is L×W, so in this case A×A=196
3. We can test this by replacing A with 14 and seeing if the answer is correct.
4. 14×14=196 is true
This can also be done by finding the square root of 196.
Lets factor 8x^2 - 10x - 25
= 8x^2 -20x + 10x - 25
= 4x(2x - 5) + 5(2x - 5) 2x-5 is common to both parts so factors are:-
= (4x + 5)(2x - 5)
So its C
