(1 point) Let x, y, z be (non-zero) vectors and suppose w = 3x + 2y – z. If z = -3x – 2y, then w = 6 X + Using the calculation above, mark the statements below that must be true. A. Span(w, x, y) = Span(w, y, z) B. Span(w, z) = Span(w, x) C. Span(w, X, Z) = Span(x, y, z) D. Span(w, x) = Span(y, z) E. Span(x, y) = Span(w, z)
