Answer:

Mr. Smith has a square sheet of glass in his garage.

Its side length is 'x'

He plans to cut 3 inches off of the sheet along the width to use it for a window.

So, he will cut 3x from the original (width x original glass side)

[tex]3\times x=3x[/tex]

Area of original square = [tex]x\times x=x^{2}[/tex]

Hence, the area of the sheet of glass after being cut is= [tex]x^{2} -3x[/tex]
