Trình bày cách mã hóa và giải mã của Caesar cho nội dung sau “Discrete Mathematics course teach students how to think logically and mathematically ” với f(p)= (p + k)
mod 26. trong đó k = 3
Ví dụ s4=3 thì f(p)= (p + 3) mod 26

it should be a and d. lmk if i'm wrong xd

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.
