## Homework Statement

Let A be the set of all vectors with length 2 and let B be the set of all vectors of length 4.

How do you show that the span of the sum of a vector in A and a vector in B is all vectors with lengths between 2 and 4?

EDIT: change 4 o 6

I tried drawing triangles but that got me nowhere. Do I actually need to write out the components or something?

Let me know if I did not explain the problem okay.
