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.
Answer:
3(16 + (─40) + 4) = -60
(─10 + 18) × (─1) = -8
Step-by-step explanation:
3(16 + (─40) + 4)
PEMDAS:
3(16+(-40)+4)
3(-24+4)
3(-20)
-60
(─10 + 18) × (─1)
PEMDAS:
(-10+18) x (-1)
8 x -1
-8
These are your answers
Hope this helps!
