Which inequality best describes the possible lengths of third side of a triangle with two sides of lengths 11 and 9

the sum of the lengths of any two sides of a triangle is always greater than the length of the third side

T=the third side

12+18>T

12+T>18

18+T>12

the first equation says that T<30

the second equation says that T>6

putting these together...

6<T<30

the sum of the lengths of any two sides of a triangle is always greater than the length of the third side

T=the third side 12+18>T, 12+T>18, 18+T>12, the first equation says that T<30 the second equation says that T>6 putting these together 6<T<30

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.
