Answer:

$3y^(2) -6y\geq 200$

Explanation:

Let

x------> the length of the deck

y------> the width of the deck

we know that

The area of Ethan's deck is

$xy\geq 200$ -----> inequality A

x=3y-6 ----> equation B

substitute equation B in the inequality A

$(3y-6)y\geq 200$

$3y^(2) -6y\geq 200$ ------> inequality that can be solved to find possible widths for Ethan's deck
