5. explain why |z + w| ≤ |z| + |w| and |z − w| ≤ |z| + |w| geometricaly. (hint: triangle inequality theorem)

Which equation and solution can be used to solve this problem? thirteen less than a number is sixteen. 13-n=16: add 13 to both sides. the answer is 29. n+13=16: subtract 13 from both sides. the answer is 3. n+16=13 subtract 13 from both sides. the answer is 3. n-13=16: add 13 to both sides. the answer is 29.
