Question

Which expression represents the determinant of mc002-1.jpg?
det(A) = (–3)(–6) – (1)(6)
det(A) = (–3)(–6) + (1)(6)
det(A) = (1)(6) – (–3)(–6)
det(A) = (–3)(–6) + (–1)(–6)

Answer 1

Answer:

Step-by-step explanation:

It represents a symmetrical matrix, that is;

det(A)= (-3) (-6) - (1) (6) = 18 - 6 = 12

det(A)= (-3) (-6) + (1) (6) = 18 + 6 = 24

det(A)= (1) (6 ) - (-3) (- 6) = 6 - 18 = -12

det(A)= (-3) (-6) + (-1) (-6) = 18 + 6 = 24
