Answer 1

To solve for \( x \) in the context of the trapezoid described, we can use the property of the median (also known as the midsegment) of a trapezoid. The median of a trapezoid is calculated by taking the average of the lengths of the two parallel sides.

In your case:
- The lengths of the parallel sides are given as 11 and 17.
- The median is given as \( 4x - 30 \).

Using the formula for the median of a trapezoid, we have:

\[
\text{Median} = \frac{\text{Length of top side} + \text{Length of bottom side}}{2}
\]

This translates to:

\[
4x - 30 = \frac{11 + 17}{2}
\]

Calculating the right-hand side, we get:

\[
4x - 30 = \frac{28}{2}
\]
\[
4x - 30 = 14
\]

Now, we need to solve for \( x \). First, we can add 30 to both sides:

\[
4x = 14 + 30
\]
\[
4x = 44
\]

Next, divide both sides by 4:

\[
x = \frac{44}{4}
\]
\[
x = 11
\]

Thus, the value of \( x \) is \( 11 \).

Looking at the options provided:

- 4
- 11
- 9
- 6

The correct answer is \( \boxed{11} \).
