help me please!!!!!!

Answer 1

C++

#include<iostream>

#include<cmath>

using namespace std;

int main() {

   float x, z, a, d, y;

   cin >> x >> z >> a >> d;

   y = sqrt(x * x + z + 1) / (abs(4 * a + d * d));

   cout << y;

   return 0;

}

#include<iostream>

using namespace std;

int main() {

   float f, x;

   cin >> x;

   if (x <= -2)

       f = x * x * x + 4;

   if (x > 2)

       f = x * x - 3;

   cout << f;

   return 0;

}

program ex2;

var

 x, z, a, d, y: real;

begin

 readln(x);

 readln(z);

 readln(a);

 readln(d);

 y:=sqrt(sqr(x)+z+1)/(abs(4*a+sqr(d)));

 writeln(y);

end.

 if (x<=-2) then

 begin

 f:=sqr(x)*x+4;
