Answer:
x = 9
Step-by-step explanation:
2 sides are 4 less than x, that is x - 4
The perimeter is the sum of all 3 sides, thus
x + x - 4 + x - 4 = 19, that is
3x - 8 = 19 ( add 8 to both sides )
3x = 27 ( divide both sides by 3 )
x = 9

Since the president and the vice president must be seated in the front, that's two ways already; p-vp, vp-p.
Three other member, let's say their names are Bill, Joe, and Nate.
b-j-n, j-b-n, n-b-j, b-n-j, j-n-b, n-j-b.
6 different combinations.
Multiply 6 by 2,
6 x 2 = 12.
There are 12 different ways.
