Question
- A. (10, 14)
- B. Not (10, 14)
- C. (10, 14) only sometimes
- D. (10, 14) with no working
Answer
The correct answer is (10, 14).
Explanation
Trace the calculation before choosing. The verified method for Vector operations and proofs gives (10, 14); no later explanation is allowed to change that value.
Common mistake
Vector operations and proofs common mistake 1
Writing a final answer without showing the method that justifies it. This can weaken answers for: [Higher only] Apply addition and subtraction of vectors and multiplication of vectors by a scalar..
Show the method first, then give the final answer in the required form. Apply this directly to Vector operations and proofs.
