Question

Please can I have help!

Answer 1

Option 2

Explanation:

First multiply each vector by the scalar in front of it as you would when expanding brackets:

`\begin{pmatrix} 0 \\ -48 \\ -60 \end{pmatrix} + \begin{pmatrix} -27 \\ 15 \\ 12 \end{pmatrix} + \begin{pmatrix} 70 \\ 10 \\ -100 \end{pmatrix}`

Now just add the numbers in each row together

`\begin{pmatrix} 43 \\ -23 \\ -148 \end{pmatrix}`

Hence the answer is the second option
