Respuesta :
The expression would be 2(3x + 9) + 2(4x - 5). Simplified, it is 14x + 8.
Answer:
14 x+8
Step-by-step explanation:
Parallelogram: A parallelogram is a special type of quadrilateral in which opposite sides are equal and parallel.
We have to find the perimeter of parallelogram
Perimeter of parallelogram= sum of all four sides
Let first side= 3 x+9
Second side= 4 x-5
third side= 3 x+9
fourth side side= 4 x-5(opposite sides of parallelogram are equal)
Perimeter= 3 x+9+ 4 x-5+ 3 x+9+ 4 x-5+
Perimeter= 14 x+ 8
Hence, Perimeter of parallelogram= 14 x+8
