Final answer:
The correct inequality for the problem is (c) 4x≥12.
Step-by-step explanation:
The correct inequality for the problem is (c) 4x≥12.
To find the inequality, we need to consider the formula for the area of a rectangle, which is length multiplied by width. In this problem, the length is given as 4 inches. Let x represent the width of the rectangle.
Therefore, the inequality becomes 4x≥12, since the area must be at least 12 square inches.
