Mohon bantuannya, sekarang. Thanks before. Diketahui matriks A=.... Sesuai gambar fi bawah, nomer 11-13

11. A (2 4)
(3 3)
Nilai (2a - A^{t} + 1)
2 (2 4) - (2 3) + 1 = (4 8) - (2 3) + 1 = (2 5)
(3 3) (4 3) (6 6) (4 3) (2 3)
12.
[tex] \binom{1 \: \: 5}{ - 4 \: 2} \binom{8 \: \: 3}{7 \: - 6} = \binom{1 \times 8 + 5 \times 7 \: \: \: 1 \times 3 + 5 \times - 6}{ - 4 \times 8 + 2 \times 7 \: \: \: - 4 \times 3 + 2 \times - 6} = \binom{43 \: \: - 27}{ - 18 \: \: - 24} [/tex]
13. E = D{t}C{t} E
[tex] \binom{ - 2 \: \: 1}{ - 3 \: \: 5} \binom{4 \: \: 1}{0 \: \: 6} = \binom{ - 2 \times 4 + 1 \times 0 \: \: - 2 \times 1 + 1 \times 6}{ - 3 \times 4 + 5 \times 0 \: \: - 3 \times 1 + 5 \times 6} = \binom{ - 8 \: \: 4}{ - 12 \: \: 27} [/tex]
[tex] \binom{ - 8 \: \: 4}{ - 12 \: \: 27} = \binom{ - 8 \: - 12}{4 \: \: \: \: \: 27} [/tex]
