Answer 1

#1 - Python 3.5.2
x = int(input('x = '))
if x>3: print ('f(x) =', -3*x+9);
else: print ('f(x) = ', x*x*x/(x*x+8))

//2 - MV C++ 10
#include <iostream>
using namespace std;
int main()
{
int a, b, c;
cin >>a>>b>>c;
cout<<(((a+b==0) || (a+c==0) || (b+c==0))? "Есть":"Нет");
return 0; 
}

//3 - FPC 2.6.4
var
x1, x2, x3, x4, y1, y2, y3, y4: longint;
begin
writeln ('x1, y1, x2, y2, x3, y3, x4, y4: ');
readln (x1, y1, x2, y2, x3, y3, x4, y4);
if (min(x2, x4)>max(x1, x3)) and (min(y1, y3)>max(y2, y4)) then
write ('S = ', (min(x2, x4)-max(x1, x3))*(min(y1, y3)-max(y2, y4)))
else write ('Не пересекаются!');
end.
