I used a dash line because the term 'less than' does not include the value itself.
Answer:
x+1+2x-6= 16
3x-5 =16
3x=16+5
3x=21
x=21/3
x= 7
VW= 2x-6 = 2(7) -6 = 14-6 = 8
First break the L into two rectangular prisms and then find the volume for each prism. Then add those two volumes together to get the L.
