?????Are the following statements true or false?1. If {u, v, w} is a linearly independent set, then {2u + 3v +6w, u + 3v, u +6w} is linearly independent.2. A subset of a spanning set can sometimes form a linearly independent set.3. If {u, v, w} is a linearly independent set, then {u + 3v, v - 6w, w} is linearly independent.4. The union of two subspaces of a vector space is always a subspace.35. There exist vectors u, v, w E R³ such that u - V, V-W, W - u span3R
