Let x, y, z be (non-zero) vectors and suppose w = 12x + 18y +4z
If z = ? 2x ? 3y, then w = 4x + 6y
Using the calculation above, mark the statements below that mustbe true.
A. Span(w, x, y) = Span(w, y)
B. Span(x, y, z) = Span(w, z)
C. Span(w, x, z) = Span(x, y)
D. Span(w, z) = Span(y, z)
E. Span(x, z) = Span(x, y, z)
