Factoring 3 out of the entire matrix divides the determinant by 3. O C. Multiplying a row by 3 multiplies the determinant by 3. O D. Dividing a row by 3 multiplies the determinant by 3. State which property of determinants is illustrated in this equation. 6 2 -6 6 2 -6 18 8 0 5 - 10 -8 9 -9 -8 9 -9 Choose the correct answer below. O A. If A and B are square matrices, then det AB = (det A)(det B). O B. If two rows of A are interchanged to produce B, then det B = - det A. O C. If one row of A is multiplied by k to produce B, then det B = k . det A. O D. If a multiple of one row of A is added to another row to produce matrix B, then det B = det A.Find the determinant by row reduction to echelon form. 15-? 16 5 28 7 Use row operations to reduce the matrix to echelon form. 15-7 16 5'" 287 Combine the methods of row reduction and cofactor expansion to compute the determinant. 1340 3230 7488 5254 The determinant is (Simplify your answer.)
