Vector u = < 11, 12> , v = < -16, 6> , and w = < 4, -5> .
match each vector operation with its resultant vector expressed as a linear combination of the unit vectors i and j. not all tiles will be used.

Step-by-step explanation:

I find the arithmetic tedious, so I like to let a calculator or spreadsheet do it. The components of the sum are the sums of the components.

___

For example, ...

  u - 5w = <11, 12> - 5×<4, -5>

  = <11 -5·4, 12 -5·(-5)>

  = <-9, 37>

  = -9i +37j
