Answer:
22.5 cm
Step-by-step explanation:
In the figure attached the graph of the problem can be seen.
Given the triangles are similar then the next proportion must be satisfied:
13.5/9 = 18/12 = x/15 = 1.5
Isolating x, we get:
x/15 = 1.5
x = 1.5*15
x = 22.5 cm
This isn't my work. Thanks to jbiain.

4x² - 3xy + 9y² - 3(5xy + 7y²)
4x² - 3xy + 9y² - 3(5xy) - 3(7y²)
4x² - 3xy + 9y² - 15xy - 21y²
4x² - 3xy - 15xy + 9y² - 21y²
4x² - 18xy - 12y²
