Answer:

D

Step-by-step explanation:

The question is about multiplication of matrices

Given matrix A as [6  -12]

                              [4     8]

 if 1/2x= A

then x=2A

A={6 -12}

    {4   8}

x=twice A or A +A

solving for 2A

2A=(2×6  2×-12)

       (2×4  2×8)

2A= (12   -24)

        (8       16)

Answer:

The correct answer is last option

| 12   -24 |

| 8      16 |

Step-by-step explanation:

It is given a matrix A

A =  | 6  -12 |

       | 4   8   |

Also given that another matrix X such that X/2 = A

We have to find the matrix X

To find the matrix X

We can write X = 2 * A

2 * A = 2 *  | 6  -12 |       =  | 12   -24 |

                 | 4   8   |            | 8      16 |

Therefore the correct answer is last option
