we are given
a · (b ×
c)
we know that
cross product of two vectors are vector
and dot product of two vectors are scalar
(b ×
c) is cross product of vectors b and c
so,(b ×
c) = vector
a ·( vector) is dot product of two vectors
so, a ·( vector) = scalar
so, this expression is meaningful
and
a · (b ×
c) = scalar..............Answer

Step by step explanation: I'm Sorry this answer is late but here! I don't really get number 2 I'm sorry.
question 1
x=-y
2x-y=-6
x=-y
2(-y)-y=-6
x=-y
y=2
x=-(2
y=2
(-2,2)
x=-2,
y=2
Question 2
-2x + 6y = 30
-2x + 6y + -6y = 30 + -6y
-2x + 0 = 30 + -6y
-2x = 30 + -6y
x = -15 + 3y
x = -15 + 3y
