7a-4=3a+27+4a
7a-4=7a+27
you sure you type the right question?
First we need to understand what is collinear and coplanar . Points that are on same plane are known as coplanar and points that are on same line are known as collinear .
Here , RLS are on the same plane but they are not on the same line . So the given three points are coplanar but not collinear .
Therefore the correct option is A.
The weight of the second one will be 4 tons
1 3/5=1.6
2 1/2=2.5
2.5×1.6=4
