(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)

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

i think the answer would be c
