Q9Multiple correct3 Marks13 Apr 2025Let AAA be a 3×33 \times 33×3 matrix such that v1,v2,v3v_1, v_2, v_3v1,v2,v3 are the columns of AAA. If det(A)=0\det(A) = 0det(A)=0, choose the correct statement(s).Av_1 = R2\mathbb{R}^2R2BW2={x∈R3∣Ax=0 where the columns of A are v1,v2,v3}W_2 = \{x \in \mathbb{R}^3 \mid Ax = 0 \text{ where the columns of } A \text{ are } v_1, v_2, v_3\}W2={x∈R3∣Ax=0 where the columns of A are v1,v2,v3}CW3={(x,y,z)∈R3∣x+y−z=0,x−y=0}W_3 = \{(x, y, z) \in \mathbb{R}^3 \mid x + y - z = 0, x - y = 0\}W3={(x,y,z)∈R3∣x+y−z=0,x−y=0}D1_{4} = { [abcd]\begin{bmatrix} a & b \\ c & d \end{bmatrix}[acbd] | a + c = 0, b + d = 0 }
