Determine whether S is a basis for R3.

S = {(4, 2, 5), (0, 2, 5), (0, 0, 5)}

S is a basis for R3.S is not a basis for R3.    


If S is a basis for R3, then write u = (8, 2, 15) as a linear combination of the vectors in S. (Use s1, s2, and s3, respectively, as the vectors in S. If not possible, enter IMPOSSIBLE.)
