Working shown, hopefully it helps
The relationship between points R , S , and T is that the sum of the RS and RT will be equal to RT that is RT=RS+ST
<h3>What are collinear points? </h3>
Collinear points are defined as the points which lie on the same line. Here we have three points R, S and T that are collinear.
We have the length equal to:
RS=5, RT=12 ST=7
So we can set the relationship as the sum of the RS and RT will be equal to RT.
So the relation will be given as:-
RT=RS+ST
hence the relationship between points R , S , and T is that the sum of the RS and RT will be equal to RT that is RT=RS+ST

The answer to your question would be B because you divide 10 by 3.5 to get 3, then you would divide 12 by 3 to get 4. Multiply them together to get 14
