Answer:
statement A
Step-by-step explanation:
If the ratio
= 
then TU is parallel to RS
=
= 
=
= 
Since the ratios are equal then line segment TU is parallel to line segment RS
Use the distributive property to multiply the right side giving you 5x+15, if you subtract 5x from each side you get 8=15 which is never true, the equation has no solution.
