Question

Could I have an answer ASAP

Answer 1

`\left[\begin{array}{ccc}9\\10\\\end{array}\right]`

Explanation:

Multiply the elements in a by 3 to obtain 3a

Then add corresponding elements in both matrices for 3a + b , that is

3
`\left[\begin{array}{ccc}2\\4\\\end{array}\right]` +
`\left[\begin{array}{ccc}3\\-2\\\end{array}\right]`

=
`\left[\begin{array}{ccc}6\\12\\\end{array}\right]` +
`\left[\begin{array}{ccc}3\\-2\\\end{array}\right]`

=
`\left[\begin{array}{ccc}6+3\\12-2\\\end{array}\right]`

=
`\left[\begin{array}{ccc}9\\10\\\end{array}\right]`
