Step-by-step explanation:
Use PEMDAS to complete the problem
PE doesn't matter, there's not parentheses or exponents
MD=Multiplication and Division. Do 3*6=9, now your problem looks like 9-4
AS=Addition and Subtraction. 9-4=5
Let x be the length of third side.
12 + x > 13
x > 1-------------(1)
13 + x > 12
x > -1 ------------(2)
by combining (1) and (2)
we have x > -1
