The vectors u = (3, 2, 4) and v = (5, 10, 20) are: a. Linearly Independent b. Linearly dependent c. Spans R3 d. None Let V be the set of all ordered pairs of real numbers, and consider the following addition and scalar multiplication operations on u = (u1, u2) & v = (v1, v2) : u + v = (u1+v1, U2+V2), ku = (O, ku2) Compute u+v, when u = (3, 5) , v = (2, 3) a. (6, 15) b. (5, 8) c. (2, 3) d. None
