Answer:
The length of UW in units is:
36 units.
Step-by-step explanation:
It is given that:
Point V lies between points U and W on.
This means that the length of the line segment UW is equal to the sum of the length of the line segment UV and VW.
i.e.
[tex]UW=UV+VW[/tex]
i.e.
[tex]9x-9=2x-4+4x+10[/tex]
on combining the like terms in the right hand side of the expression we have:
[tex]9x-9=2x+4x-4+10\\\\9x-9=6x+6[/tex]
Now on combining the like terms we have:
[tex]9x-6x=6+9\\\\i.e.\\\\3x=15\\\\x=\dfrac{15}{3}\\\\x=5[/tex]
Hence,
[tex]UW=9\times 5-9\\\\i.e.\\\\UW=9(5-1)\\\\i.e.\\\\UW=9\times 4\\\\UW=36[/tex]
