Answer:
35.770
Step-by-step explanation:
If the number behind the hundreths place is bigger than the hundreths place then you round up 1
Matrix B has dimensions 4x3
Matrix C has dimensions 3x4
Write out those dimensions like so: 4x3 3x4
The inner '3's match up so B*C is possible. The dimensions of B*C is 4x4 as these are the outer dimensions when lining up 4x3 3x4
Since B*C is a square matrix, it is possible that an inverse could exist. Keep in mind that this isn't a guarantee as the determinant of B*C could be zero (which would lead to BC being non-invertible). Though of course we'd need more info.
