Pembahasan

Diketahui titik awal straight Oa with rightwards arrow on top equals stack O A with rightwards arrow on top semicolon b with rightwards arrow on top equals stack O B with rightwards arrow on top semicolon c with rightwards arrow on top equals stack O C with rightwards arrow on top, vektor-vektor tersebut dapat digambarkan sebagai berikut

CD with rightwards arrow on top equals b with rightwards arrow on top comma space BE with rightwards arrow on top equals a with rightwards arrow on top comma space DP with rightwards arrow on top equals OE with rightwards arrow on top, vektor dikatakan sama jika memiliki arah yang sama dan ukuran yang sama, sehingga vektor-vektor tersebut dapat digambarkan sebagai berikut

table attributes columnalign right center left columnspacing 0px end attributes row cell stack O B with rightwards arrow on top end cell equals cell b with rightwards arrow on top comma space BE with rightwards arrow on top equals a with rightwards arrow on top comma end cell row cell DP with rightwards arrow on top end cell equals cell OE with rightwards arrow on top end cell row blank equals cell stack O B with rightwards arrow on top plus BE with rightwards arrow on top end cell row blank equals cell b with rightwards arrow on top plus a with rightwards arrow on top end cell row blank equals cell a with rightwards arrow on top plus b with rightwards arrow on top end cell end table

Sehingga didapatkan gambar akhir sebagai berikut

 vektor posisi straight P yaitu

 table attributes columnalign right center left columnspacing 0px end attributes row cell stack O P with rightwards arrow on top end cell equals cell stack O C with rightwards arrow on top plus stack C D with rightwards arrow on top plus stack D P with rightwards arrow on top end cell row blank equals cell c with rightwards arrow on top plus b with rightwards arrow on top plus a with rightwards arrow on top plus b with rightwards arrow on top end cell row blank equals cell a with rightwards arrow on top plus 2 b with rightwards arrow on top plus c with rightwards arrow on top end cell end table,

Oleh karena itu, jawaban yang benar adalah D. undefined
