Extracted text: Determine whether the set W is a subspace of R3 with the standard operations. If not, state why. (Select all that apply.) W = {(x1, X2, X4X2): X1 and x2 are real numbers} O W is a subspace of R3. O w is not a subspace of R3 because it is not closed under addition. O w is not a subspace of R3 because it is not closed under scalar multiplication. Submit Answer
