Answer:
12<x≤12.2
Step-by-step explanation:
To fit in an existing frame, the length, x, of a piece of glass must be longer than 12 cm but not longer than 12.2 cm.
The length of frame is x cm.
Length of frame must be longer than 12 cm.
Inequality, x>12
Length of frame not longer than 12.2 cm
In equality, x≤12.2
Now we make compound inequality of question
"Length of frame, x must be longer than 12 cm and not longer than 12.2 cm"
Inequality: 12<x≤12.2
Length of glass fit in the frame, 12<x≤12.2
Hence, The inequality 12<x≤12.2
