ways.

The answer is B. 495.
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
1/2 + 1/4 = 3/4
3/4 + 1/4 = 1
I think the answer is A.33 not a polunomial
2*&/45/+=67364/3/4/32:5,6544 is hothead answer
