Pembahasan Soal:

Dengan menggunakan konsep perkalian matriks diperoleh

table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell open square brackets table row 1 cell negative 1 end cell 5 row cell negative 2 end cell 3 6 end table close square brackets cross times open square brackets table row 1 cell negative 1 end cell row 4 0 row 7 cell negative 5 end cell end table close square brackets end cell row blank equals cell open square brackets table row cell 10 open parentheses 1 close parentheses plus open parentheses negative 1 close parentheses 4 plus 5 open parentheses 7 close parentheses end cell cell 10 open parentheses negative 1 close parentheses plus open parentheses negative 1 close parentheses 0 plus 5 open parentheses negative 5 close parentheses end cell row cell negative 2 open parentheses 1 close parentheses plus 3 open parentheses 4 close parentheses plus 6 open parentheses 7 close parentheses end cell cell open parentheses negative 2 close parentheses open parentheses negative 1 close parentheses plus 3 open parentheses 0 close parentheses plus 6 open parentheses negative 5 close parentheses end cell end table close square brackets end cell row blank equals cell open square brackets table row cell 10 minus 4 plus 35 end cell cell negative 10 plus 0 minus 25 end cell row cell negative 2 plus 12 plus 42 end cell cell 2 plus 0 minus 30 end cell end table close square brackets end cell row blank equals cell open square brackets table row 41 cell negative 35 end cell row 52 cell negative 28 end cell end table close square brackets end cell end table

Dengan demikian hasil dari table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell open square brackets table row 1 cell negative 1 end cell 5 row cell negative 2 end cell 3 6 end table close square brackets end cell end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cross times end table table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell open square brackets table row 1 cell negative 1 end cell row 4 0 row 7 cell negative 5 end cell end table close square brackets end cell end table adalah table attributes columnalign right center left columnspacing 0px end attributes row blank blank cell open square brackets table row 41 cell negative 35 end cell row 52 cell negative 28 end cell end table close square brackets end cell end table.

Oleh karena itu, jawaban yang benar adalah D.
