Question

franklin is drawing a rectangle. the length will be 5 inches, and the area will be at least 20 square inches. let x represent the width of the rectangle. which inequality describes the problem? 5x ≤ 20 5x ≥ 20 solve the inequality. then, complete the sentence to describe the solution. the rectangle will be at least
inches wide. submit

Explanation:

Step1: Select correct inequality

The area of a rectangle is $\text{length} \times \text{width}$. The area is at least 20, so $5x \geq 20$.

Step2: Isolate x (divide by 5)

Divide both sides by 5:
$\frac{5x}{5} \geq \frac{20}{5}$

Step3: Simplify to find x

$x \geq 4$

Answer:

Correct inequality: $5x \geq 20$
The rectangle will be at least 4 inches wide.
