perimeter = (3x + 7) + (4x - 9) + (5 x+ 6)
= 12x + 4
=4(3x+1)

P = 3x + 7 + 4x - 9 + 5x + 6
P = 12x + 4
P = 4(3x + 1)

P = (3x + 7) + (4x - 9) + (5x + 6)
P = 3x + 7 + 4x - 9 + 5x + 6
P = 3x + 4x + 5x + 7 - 9 + 6
P = 12x + 4
P = 4(3x + 1)

add the like terms together
the x terms: 3x + 4x + 5x = 12x
the constants: 7 -9 +6 = 4
so the perimeter is 12x + 4

Just add all the sides up i.e:
(3x + 7) + (4x - 9) + (5x + 6) = 12x + 4
