Rectangle perhaps?
P = 2 (3x - 4) + 2 (7x + 10)
P = 6x - 8 + 14x + 20
P = 20x + 12

If two of the sides are the same in this problem, then 2 sides are 3x - 4 and the other two sides are 7x + 10.
To find the perimeter, add the four sides together:
P = (2)(3x - 4) + (2)(7x + 10)
P = 6x - 8 + 14x + 20
P = 20x + 12
The answer is P = 20x + 12

Assuming that (3x-4) and (7x+10) represents the sides of a rectangle, then the perimeter is:
p = 2(3x - 4) + 2(7x + 10)
p = 6x - 8 + 14x + 20
p = 20x + 12

Perimeter of a rectangle:
P=2(length)+2(width)
=2(3x-4)+2(7x+10)
=6x-8+14x+20
Perimeter of a rectangle=20x+16

If one side is (3x-4) and the other is (7x+10) and you have four sides total. Two of each different length. You would have:
2(3x-4) + 2(7x+10)
distribute:
6x-8 + 14x + 20
Add like terms
20x +12

Though your question is incomplete,assuming that the sides represent the sides of a parallelogram,the perimeter is
2(3x-4+7x+10)
=2(10x+6)
=20x+12

"its" as in what? What are those two expressions supposed to represent? Adjacent sides of a rectangle? Something else?
