Answer:
Step-by-step explanation:
According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that you cannot draw a triangle that has side lengths 2, 7 and 12, for instance, since 2 + 7 is less than 12.
Yes the answer is not 4/7 its 7/4
9(3n + 8) = 180
3n + 8 = 180/9
3n + 8 = 20
3n = 20 - 8
3n = 12
n = 12/3
n = 4 <==
