We have the following vectors:
u = (a, b)
v = (c, d)
We observe that the vectors form an angle of 90 degrees.
Therefore, the product u.v is equal to zero.
We have then:
u.v = (a, b). (c, d) = 0
u.v = ac + bd = 0
ac = -bd
Answer:
B) ac = -bd

To get the simplest form of a fraction, simplify or solve it as far as it can be solved. In the case of this fraction for example, both 6 and 18 are divisible by 2. Divisible means both these numbers can be divided by 2.
when we divide them by 2 we get 3 instead of 6 on top and 9 instead of 18 agh the bottom.
6/18 = 3/9
Now 3/9 are both numbers that can further be divided because they can both be divided by 3
this division will give us
1/3 is the answer. This is the simplest form of the fraction 6/18.
