Find the inverse of the given matrix, if it exists. 1 -2 1 A= -2 5 -3 W N 3-5 2 Find the inverse. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA A¹= (Type an integer or decimal for each matrix element.) (... O B. The matrix A does not have an inverse.

Perform the indicated matrix operations. If an expression is undefined, explain why. Let C= 12 -31 Find 4C-2E -5 [+] 4 and E= OA. 4C-2E= (Click on the answer box and then select the matrix icon below) B. The expression 4C-2E is undefined because 4C and 2E have different dimensions. OC. The expression 4C-2E is undefined because the number of rows in C is not equal to the number of columns in E. O D. The expression 4C-2E is undefined because E is not a square matrix.
