04 -51 (1 point) leta -5 0 we can find the determinant of a by using row reduction: l-20-25 -1 -4-5 01 first we swap the first and second rows to get0 4-5 l-20 -251j by what factor does this change the determinant? 20 25 0 next we multiply the first row by-5 to get 0 4-5 -20-25-1 by what factor does this change the determinant? [20 25 0 finally we replace the third row by the sum of itself and the first row to get 0 4 -5 0 0 1 by what factor does this change the determinant? since the determinant of the row reduced matrix is the determinant of a is
