Solution

The problem in the image asks about the width of a rectangle. The problem is stated as follows:


Question: The width of a rectangle is two more than 12x\frac{1}{2}x centimeters, and its length is two less than 34x\frac{3}{4}x centimeters. Which equation represents the relationship between the width and the length of the rectangle?

Answer Choices:

  1. 3x8=2x+23x - 8 = 2x + 2
  2. 2x+10=3x82x + 10 = 3x - 8
  3. x2=14x+2xx - 2 = 14x + 2x
  4. 2x+18=x22x + 18 = x - 2

Let's define the width (ww) and the length (ll) of the rectangle based on the information provided:

  • Width: w=12x+2w = \frac{1}{2}x + 2
  • Length: l=34x2l = \frac{3}{4}x - 2

We are looking for the equation that correctly represents the relationship between the width and the length.

Let's consider each option:

  1. 3x8=2x+23x - 8 = 2x + 2

    • This equation does not match the form of ww and ll provided.
  2. 2x+10=3x82x + 10 = 3x - 8

    • This equation seems to be incorrectly formed because neither side matches the expressions for ww or ll.
  3. x2=14x+2xx - 2 = 14x + 2x

    • This equation does not align with the expressions derived.
  4. 2x+18=x22x + 18 = x - 2

    • Again, this equation does not represent the relationship between the width and length as defined.

None of the provided answer choices directly match the standard relationship between width and length given in the problem.

However, let's analyze the form of the expressions:

Given:

  • w=12x+2w = \frac{1}{2}x + 2
  • l=34x2l = \frac{3}{4}x - 2

Since no direct formula matching the options is provided, a typical relationship to check could involve verifying if there is some manipulation of these expressions that matches the options. But since this is not the case here, the problem might have an error, or it may expect a specific form from the provided choices.

Relative Questions:

  1. How do you typically determine the relationship between the width and length of a rectangle?
  2. Can you derive another equation if additional constraints were provided?
  3. What would happen if xx were a specific value? How would the width and length relate then?
  4. How can you check the validity of each equation in such problems?
  5. Could this problem involve a different interpretation of algebraic manipulation?

Tip: Always recheck the algebraic manipulation to ensure the relationship between variables is consistent with the problem's description.
