Answer:
F. -15 + 9i
Step-by-step explanation:
B = (-7 -6i)
Multiply B by F = (-15 + 9i), would give;
B × F = (-7 -6i) × (-15 + 9i)
= -7 (-15 + 9i) - 6i (-15 + 9i)
= 105 -63i + 90i - 54(
)
But
= -1, so that:
105 -63i + 90i -54(
) = 105 -63i + 90i -54(-1)
= = 105 -63i + 90i + 54
= 159 + 27i
B × F = 159 + 27i
Thus the required complex number is F (-15 + 9i).
Answer is x = 4
Explanation :-
As B is midpoint of SR :- SB = BR and if. SR = 6x then SB = 3x
AC parallel SR ( MID POINT THEOREM )
Hence AC parallel SB
Similarly , AB parallel CS (MID POINT THEOREM)
So ABCS is a parallelogram
And we know that in parallelogram opposite sides are equal so AC = SB
So now we have AC = 5x - 8 and SB = 3x
So, 5x - 8 = 3x
5x - 3x = 8
2x = 8
x = 4
