Tolong yaa soal nomer 1 sampek 5

1).u=AB
AB=B-A
=(-3,10,-14) - (3,1,-2)
=(-6,9,-12)
v=AC
AC=C-A
=(1,2,1)-(3,1,-2)
= (-2,1,3)
1/3u + 2v
=1/3(-6,9,12) + 2(-2,1,3)
=(-2,3,4) + (-4,2,6)
=(-6,5,10)

2).caranya sama seperti no 1

3).a= (3,-2p,-1), b =(p, 6,3) ,c (-5,4q,2)
jika a + b = c
=(3,-2p,-1) + (p, 6,3) = (-5,4q,2)
=(3+p , -2p+6 , 2) = (-5 ,4q , 2)
3+p = -5
p = -8
-2p+6 = 4q
-2(-8)+6 = 4q
16 + 6 = 4q
22 = 4q
22/4=q
11/2 = q

maaf ya cuma itu :)
koreksi lagi ya...
