State the row operation performed below and describe how it

State the row operation performed below and describe how it affects the determinant [a b c d], [a b 3c 3d] What row operation was performed? A. The row operation adds 3 to row 2. B. The row operation scales row 2 by 3. C. The row operation subtracts 3 from row 2. D. The row operation scales row 2 by one-third. How does this affect the determinant? A. The determinant is 0. B. The determinant is multiplied by 3. C. The determinant is divided by 3. D. The determinant is unchanged.

Solution

What row operation was performed?

ans B) the row operation scales row by 2 by 3

how does this effect the determinant?

Ans : B) the determinant is multiplied by 3
