Let A be a 3 x 3 matrix given by -3 10

Let A be a 3 x 3 matrix given by -3 10 A = 0. I+ 3 -6 0. 0. (a) Calculate the determinant of A Give your answer in the box below. det(A) = %3D (b) Find all for which the matrix A is not invertible Part (b) Syntax advice: If there are multiple values of r, these values should be separated by a comma. For example, if your z values are a, b, c please enter a, b, cin the box. (c) Your classmate Bella wants to calculate the determinant of M = A4+2A without calculating the entries of M explicitly %3D Show your classmate how this can be done by giving your answer in the essay box below Eguation Editor A-A-T BIUS x, x
