Yes, since you can multiply 2/5 numerator and denominator to get the rest of the fractions, it makes them all equivalent.
Let
be the line given by the vector equation
.
First, we use the director vectors of the lines L1 and L2 to get the
vector equation of the plane containing them, which we denote by
. This is,

We observe that
. Therefore, the vector equation of
defines a plane and
is a normal vector to 
Finally, the vector equation for the wanted plane, which we denote by
, is
Thus, if
, then
and since
is parallel to
, then it is perpendicular to
.
Answer:
the option c is the answer for this question
There are a few ways to go about doing this, but the easiest is portably to break it up into three shapes: two identical triangles, and a rectangle. The area of one triangle is:
1/2 (10x8) = 40, so the area of two triangles is 80.
The area of the square is 20 x 8, which is 160.
The total area is the sum of the two:
80 + 160 = 240, and this is your total area.
Answer:

Step-by-step explanation:
A inequality is given to us and we need to find the solution set . The inequality given to us is :-

This means that x belongs to Real Numbers. Hence final answer would be :-
