Det= (3*8) - (3*2) - 8 Answer:
Det= 48
Step-by-step explanation:
The given matrix is one of the form:
{3 3 1
-2 0 -2
-2 4 -3]
The Sarrus's law says that we can solve the matrix as the image attached (please take a look).
Then, the determinant is :
Det= 3*(0)*(-3) +1*(-2)*(4) +(-2)*(-2)*(3) - 1*(0)*(-2) - 3*(-2)*(3) - 3*(-2)(4)
Det= 0 -8 +12 +0 +18 +24 = 48
