Attention all math addicts. I need some help, and here are 2 problems:

1. If an n x n matrix A has at least two dependent rows, then det(A) = 0. True or False? and why?

2. Find all 3 x 3 matrices for which e is an enigenvector with associated eigenvalue "lamda" = 5

I want to get this over with. Thanks for the help, and sorry to those who get pissed at these type of threads
