Sound or vibration wave that is conducted
Answer:
12
Step-by-step explanation:
Since 8 poster takes 48 inches of tape
48/8 = 6
each poster will take 6
if you have two posters
6x2=12
so 12
Y=2+1
2+1=3
So y=3
The answer is y=3
The area is 270 inches, because you would do length times width, which in this situation is 28 and 15. You multiply them, and you get 270.
