Answer:
15 days
Step-by-step explanation:
Let x be the number of days needed for B to complete the job. Then x-5 is the number of days needed for A to complete the job.
In 1 day,
- A completes of all work;

Hence, in 1 day both A and B complete of all work. A and B working together can do a work in 6 days. Then
Solve this equation:
If then that is impossible. So, B needs 15 days to complete the work alone.

Step-by-step explanation:
To find the scale factor of a dilation, we first find two corresponding sides. For example, the top edge of the black shape corresponds with the top edge of the purple shape. The top edge of the black shape measures 15 units while the top edge of the purple shape measures 3 units
Now, we divide the length taken from the figure by the length taken from the original shape. In this case, we divide the length of 3 by the length of 15.
