Answer:
2(x-4) + 2(2x+8) OR long way (x-4) + (x-4) + (2x+8) + (2x+8)
Step-by-step explanation:
2(x-4) represents the (x-4) + (x-4) in the longer version since for perimeter you add the sides. Same thing for the other side, 2(2x+8) represents (2x+8) + (2x+8).
Not sure if you need the expression solved but here:
[tex]2(x-4) + 2(2x+8)\\(2x-8) + (4x+16)\\=6x+8[/tex]
To get from first line to second, use distributive property. To get from second to third line, combine like terms.
