QRS has been dilated to form TUV. What is the length of QS?

Answer:
C. 2
Step by step explanation:
In this case, you can use the similarity of triangles.
[tex]\frac{x}{a}=\text{ }\frac{y}{b}\text{ = }\frac{z}{c}[/tex]X= 35
Y = 5
a =14
b = ?
Then we replace.
[tex]\frac{35}{14}=\frac{5}{?}[/tex][tex]\text{? = }\frac{5\cdot14}{35}[/tex][tex]\text{? = 2}[/tex]
