Answer:
Step-by-step explanation:
a) We have 15! as the product of 1 to 15 natural numbers. Since 17 is prime there will be no factor common to these
By actual division we find
15! (mod 17) =16
From this we deduce
even 16! mod 17 = 16 = -1
According to Wilson theorem
(17-1)! = -1 mod 17
Thus verified 17 is prime
Hence 15! (mod 17) =-1=16
-----------------------
b) 2(26!) is divided by 29
Since 29 is prime
(29-1)! = -1 mod 29
28! = -1 mod 29 = 28
When divided this gives 25 as remainder
Divide the number of actual pages by 2.
52/2 = 26

There is a square and a triangle
the area of a square is
A = b * h
A = 2*2
A = 4
the area of the triangle is
A = (b*h)/2
A = (2 *2)/2
A = 4/2
A = 2
Now we add them up to find the total area
4 + 2 = 6
The shape has an area of 6 units^2
