Answer:
18cm
Step-by-step explanation:
Given:
- The length of AB is 9 centimeters
- A dilation with a scale factor of 2
The length of the image AB after the dilation is applied:
9 x 2 = 18
dilation is used to make an image or in this case AB, with a scale factor of 2 means that its doubling in size. If the scale factor was 1/2 that it would be decreasing in size since it will be half of the original size
Y= -2x+4 m represents the x value and b the y intercept
16 mph is the answer I found after doing the work
23. Kim and Jay leave at the same time to travel 25 miles going to the beach.
Kim drives 9 miles in 12 minutes
Jay drives 10 miles in 15 minutes.
Question: who will arrive first?
Unit rate of Kim
=> 9 miles in 12 minutes
=> 0.75 miles / minutes
=> 25 / 0.75
It will take 33.33 minutes for Kim to arrive
Unit rate of Jay
10 miles in 15 minutes.
=> 10 miles /15 minutes
=> 0.67 miles /minute
=> 25 / 0.67
It will take Jay 37.31 minutes to arrive at the beach.
SO Kim will arrive first

Step-by-step explanation:
First off if it is true in inches you could use a ruler to measure the bottom it works if you are desperate a lot of the time. Also the bottom of the trapezoid is 6 meters. If you didn't know the perimeter you could split the trapezoid into a rectangle and a triangle. You just have to take off the irrelevant sides when you put it together. So you take the 2 meters from the top of the trapezoid and then the bottom of the triangle is 4, so just split up the trapezoid and find the perimeter of the triangle and rectangle.
