1.If A=[x111x111x]A = \begin{bmatrix} x & 1 & 1 \\ 1 & x & 1 \\ 1 & 1 & x \end{bmatrix}A=x111x111x and B=[x111x111x]B = \begin{bmatrix} x & 1 & 1 \\ 1 & x & 1 \\ 1 & 1 & x \end{bmatrix}B=x111x111x, then ∣A∣|A|∣A∣ is equal toa.3B+I3B + I3B+Ib.3B3B3Bc.−3B-3B−3Bd.I−3BI - 3BI−3BLogin to continueOnly logged in users canattempt or see the solution.
