3x -7 = 5x + 19
-7 = 2x + 19
-26 = 2x
x= -13
The two numbers can be any factors of 120. This includes: (1,120) (2,60)(3,40)(4,30)(5,24)(6,20)(8,15)(10,12) and the reverse of this. The smallest perimeter would be the two numbers that are closer together, which is 10 and 12.
False, the answer actually comes out to be -1
