Use as many columns of A as possible to construct a matrix B with the property that the equation Bx = 0 has only the trivial solution. 3 -3 -9 6 -4 -4 7 A = 6 -2 10 12 13 O 24 18 19 B =

you have to use each of these a. A+B  b. A-B c. -4A  d. 3A+2B to solve the matrix

Compute the sum of A = 85 63 and B = 2a 4b - 3c - 8d possible A+B= (Simplify your answer. Type an expression for each matrix element. Use integers or fractions for any numbers in the expression.) JA الله S Nex

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.
