Answer:

  1. var a = 5;
  2. var b = 2;
  3. var c = 7;
  4. a = a + b;  
  5. b = a + b;
  6. c = a + b;
  7. console.log(a);
  8. console.log(b);
  9. console.log(c);

Explanation:

Line 7 - 9

Use console.log to display variable a, b and c to terminal and we will get the result as below

7  

9

16

The a is 7 because a = a + b = 5 + 2 = 7

The b is 9 because b = a + b = 7 + 2 = 9

The c is 16 because c = a + b = 7 + 9 = 16
