Answer:

[tex]QV=13\ units[/tex]

Step-by-step explanation:

we know that

A median of a triangle is a line segment from one vertex to the mid point on the opposite side of the triangle.

so

In this problem

If QU is a median of triangle UVW

then

QV=QW

substitute the given values

[tex]7x-1=4x+5[/tex]

Solve for x

[tex]7x-4x=5+1[/tex]

[tex]3x=6[/tex]

[tex]x=2[/tex]

Find out the length of segment QV

[tex]QV=7x-1[/tex]

substitute the value of x

[tex]QV=7(2)-1=13\ units[/tex]
