Question

Perform the matrix operation.2 3Given A =25and B =04-1 6find 2A + B.A4 103 1610]B-3 11D4 142 22

Answer 1

step 1

Find 2A

Multiply by 2 each number of the matrix A

so

2A= 4 6

4 10

step 2

Find out the sum 2A+B

so

2A+B= (4+0) (6+4)

(4-1) (10+6)

2A+B= 4 10

3 16

therefore

the answer is the option A
