Answer:
5(n-4)(n+4)
Step-by-step explanation:
given that
5n²-80
first we take common factor.
5(n²-16)
now we use the sum product pattern
5(n²+4n-4n-16)
We take common factor from pairs
5(n(n+4)-4(n+4))
5(n+4)(n-4).

Answer: 745
Step-by-step explanation: if there were initialy 80 books and its increasing by 25% every month, for month 1 we have:
25% = 0,25
increase is 1+0.25
M1 = 80.(1+0.25)¹ = 80.1.25 = 100
M10 = 80 (1+0.25)¹⁰ = 80. 9.313225 = 745.05 (end of the month)
