Best ResponseYou've already chosen the best response.0Because you and i made the same mistake, we only read the first part of the question and "ignore" the second sentence.

Best ResponseYou've already chosen the best response.1sum of three sides is less than 18 5+6+x<18 subtract 11 on both sides x<7 now it cant be 0 or a negative integer

Best ResponseYou've already chosen the best response.1well look if it will be less than 1 then sum of two sides wont be greater than the third side ;)

Best ResponseYou've already chosen the best response.1i think i understood it already see if the othe side is 1 then 5 + 1 would be equal to 6 right? since we need the third to be greater and not equal to the sum then we use 2 and 2 is greater than 1 so if we would put it in a situation where x = 2 then we'll get 5 + 6 + 2 < 18 13 < 18 5+6 > 2 11 >2 5+2 > 6 7>6 6 + 2 > 5 8 > 5

Best ResponseYou've already chosen the best response.0We must fulfill the second sentence criteria to find the range of values of x hence, the range would be 1<x<7
