The answer is C
Every Biconditional Statement has 'If and only if' in it
Hope this helps :)
Divide off -3 from both sides, that leave you with:
n + 5 = -4
Subtract the 5 to the other side
n = -9
Triangular inequality: Length of third side must be less than the sum of the lengths of the other 2 sides.
x < 18 + 29
x < 47
so Maximum length of third side is 46 units.
Also 29 < 18 + x
x > 11 so minimum length = 12
Difference = 46-11 = 35
Personally i think that if you use the pi symbol it would be more accurate because on a calculator there is an pi symbol √ which is the same it will give you an answer closer to an whole number.
