Question 12422: Hello,

I would appreciate it if a tutor could please help me verify my work for the below problem.

Find the determinant of matrix A = [-6, 4, 3, 5]. Matrix A is a 2x2 square matrix with -6 positioned above 4 and 3 positioned above 5.
det A = (-6)(5)-(3)(4)
det A = -30 - 12= -42
det A = -42

In advance, thank you for your assistance!
