Question

I need help with number 28 I could be wrong but I think you need to use the rook to match the bishop number 25

Answer 1

2 translation vectors.

`(A,3)\text{ }+\text{ u(4,0) }=\text{ (E,3)}`
`(E,3)\text{ + u(0,4) = (E, 7)}`

Step by step explanation:

You have to move a rook from the green circle to the blue one.

Then you have to represent series of the translation vector

You should know that the tower only moves horizontally or vertically.

You first move it 4 blocks to the right

`(A,3)\text{ }+\text{ u(4,0) }=\text{ (E,3)}`

Then you move 4 blocks up.

`(E,3)\text{ + u(0,4) = (E, 7)}`
