Rotations, reflections, translations, and dilations are all different types of transformations. Rotations rotate or turn the shape around the axis. Reflections mirror the shape across the axis. Translations move the shape up, down, left, or right. Dilations make the shape a different size.

2n + 9
let the number be n then twice the number is 2 × n = 2n
and 9 more than this means add 9 to, hence 2n + 9 is the expression
Answer:
9/2 inches or 4 1/2
Step-by-step explanation: Try to find the unit rate FIRST. Divide 2 on both sides and you will get that ONE INCH = 3/2 miles.
Since you need to know the distance for 3 inches, MULTIPLY both SIDES by 3, and you will get 3 INCHES = 9/2 MILES.
