$QV=13\ units$

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.

In this problem

If QU is a median of triangle UVW

then

QV=QW

substitute the given values

7x-1=4x+5

Solve for x

7x-4x=5+1

3x=6

x=2

Find out the length of segment QV

QV=7x-1

substitute the value of x

$QV=7(2)-1=13\ units$

This is not fun

so
we mutiply the number of rows of the first matrix by the number of collumns of the second matrix

3*2 is the dimentions of the resulting matrix
you have
$
\left[\begin{array}{cccc}9&4&8&6\\2&0&3&1\\1&-2&5&0\end{array}\right]
 
\left[\begin{array}{cc}12&2\\15&1\\3&9\\8&11\end{array}\right]
 =$ $\left[\begin{array}{cc}9*12+4*15+8*3+6*8&9*2+4*1+8*9+6*11\\2*12+0*15+3*3+1*8&2*2+0*1+3*9+1*11\\1*12+-2*15+5*3+0*8&1*2+-2*1+5*9+0*11\end{array}\right]$ = $\left[\begin{array}{cc}108+60+24+48&18+4+72+66\\24+0+9+8&4+0+27+11\\12+-30+15+0&2+-2+45+0\end{array}\right]$ = $\left[\begin{array}{cc}240&160\\41&42\\-3&45\end{array}\right]$
