TU

To determine the numerical length of \( \overline{TU} \), given that \( TU = 4x - 10 \), we need to first find the value of \( x \).

However, from the information provided, it seems there isn't an equation directly allowing us to solve for \( x \) unless we use some additional geometric relationships. Assuming you are working with a geometric figure like a triangle or a line segment where \( S \), \( T \), and \( U \) are collinear points, and knowing the relationships between these points would help.

Given the information:

- \( ST = 4x - 4 \)
- \( TU = 4x - 10 \)
- \( SU = 5x + 1 \)

If \( S \), \( T \), and \( U \) are collinear and \( T \) is between \( S \) and \( U \), then \( SU = ST + TU \).

Thus, we can set up the equation:

\[
SU = ST + TU
\]

Substitute the given expressions:

\[
5x + 1 = (4x - 4) + (4x - 10)
\]

Simplify the equation:

\[
5x + 1 = 8x - 14
\]

Now, solve for \( x \):

\[
5x - 8x = -14 - 1
\]

\[
-3x = -15
\]

\[
x = 5
\]

Now that we have the value of \( x \), substitute it back into the expression for \( TU \):

\[
TU = 4x - 10 = 4(5) - 10 = 20 - 10 = 10
\]

Thus, the numerical length of \( \overline{TU} \) is **10**.

Here are some related questions:
1. What are collinear points, and how do they influence the equation setup?
2. How do you determine which segment is longer using algebra?
3. What are some other geometric interpretations of \( S \), \( T \), and \( U \)?
4. How would the solution change if \( T \) was not between \( S \) and \( U \)?
5. How can this method be applied to other line segment problems?

**Tip:** Always double-check that the points are collinear or follow the specific geometric relationship before setting up equations in geometry problems.
