Perimeter is the sum of all three sides so in this case x+(3x+2)+(3x+2). They also gave us the perimeter which is 39 so 39= x+(3x+2)+(3x+2) Simplify so 39=7x+4. [x+3x+3x=7x and 2+2=4] Then get x by itself so subtract 4 from both sides. 35=7x Then divide both sides by 7 to get x by itself. Which leaves us with X=5
Step-by-step explanation: the smallest the other two can be is 1 so you have to multiply 8 with 3, that equals 24, then you have to subtract 2 (1+1) and that gives you 22.
