(1 point) let x, y, z be (non-zero) vectors and suppose w = 8x + 16y + 2z. if z = -2x – 4y, then w = 2 x+ 6 y. using the calculation above, mark the statements below that must be true. a. span(w, x) = span(x, y) b. span(x, y, z) = span(w, x, z) c. span(x, z) = span(w, z) d. span(w, y, z) = span(w, y) e. span(w, z) = span(w, y)
