Answer:
Step-by-step explanation:
Given that
Algebra book=1
Geometry book=1
Chemistry book= 1
English book= 1
Health book= 1
Total number of books N = (1+1+1+1+1)= 5
Permutation is used to determines the number of possible arrangements in a set when the order of the arrangements is crucial.
Number of arrangements = N!
Number of arrangements= 5*4*3*2*1= 120
(x,y)= (10 -2)
9 3
there’s supposed to be lines under the 10 in the -2
y here's how you count by 5 10 15 20 25 30 35
