Linear Algebra - Vectorial Subespaces

Homework Statement

It's about Linear Algebra and vector spaces. I've tried it but i can't get the solution...:

In C$$^{5}$$, the vectorial subespace U generated for (1,2,-1,-1,2), (0,2,-1,0,-2), (00,2,-1,0) and the vectorial subespace V generated for (3,3,0,-5,2), (1,1,0,-3,2), (1,1,0,1,-2).

I have to find a base and the dimension of the vectorial subespaces U, V, U+V and U $$\cap$$V. Do U and V define the same vectorial subespace?

None.

Thank you!
