Let's solve the problem step by step.

Given the rectangle with the following dimensions:

• One side is labeled $4x + 5$.
• The opposite side is labeled $4x - 2$.
• Another side is labeled $x - 4$.

Since opposite sides of a rectangle are equal, we can set up the equation: $4x - 2 = x - 4$

To solve for $x$, we perform the following steps:

1. Subtract $x$ from both sides: $4x - 2 - x = x - 4 - x$ $3x - 2 = -4$

2. Add 2 to both sides: $3x - 2 + 2 = -4 + 2$ $3x = -2$

3. Divide both sides by 3: $x = -\frac{2}{3}$

However, the given answer states that $x = 6$. Let's recheck the steps or any given details in the problem for a possible mistake.

Revisiting the problem:

Given dimensions: $4x - 2$ $4x + 5$ $x - 4$

Reevaluating the equation $4x - 2 = x - 4$:

1. Subtract $x$ from both sides: $4x - 2 - x = x - 4 - x$ $3x - 2 = -4$

2. Add 2 to both sides: $3x - 2 + 2 = -4 + 2$ $3x = -2$

3. Divide both sides by 3: $x = -\frac{2}{3}$

To verify: $4x - 2 = x - 4$ Substituting $x = 6$: $4(6) - 2 = 6 - 4$ $24 - 2 = 2$ $22 \neq 2$

Since the equation doesn't hold, there must be a mistake in the given answers. Please verify if there is any other information provided or correct the given answers.
