Rectangle RSTU undergoes a dilation centered at the origin. The result is rectangle R'S'T'U'. Which rule describes the dilation?

Answer:
The rule is as follows:
x'=5*x
y'=5*y
Step-by-step explanation:
Each coordinate gets scaled by a factor of 5.
For example:
R(-2,0) --> R'(-10,0) [-2-->5*(-2), 0-->0]
and similarly with the other points S, T, and U
