Question

Find the value of A+2B A=[4 1 2 0] B=[-2 0 1 3]

Answer 1

Answer:

Step-by-step explanation:

The matrices are in order A= 1x4 and B =1x4

A = [4  1  2  0 ]

B = [ -2  0  1   3  ]

2B = 2 [ -2  0  1  3 ]

    = [ -4  0  2  6 ]

A + 2B = [ 4  1  2  0 ] +  [ -4  0  2  6  ]

A + 2B = [  4-4  1+0   2+2   0+6 ]

A+ 2B= [ 0  1  4  6  ]
