no. this is because a triangle’s short sides added together must be equal to or dreamer than the length of the longest side. for example a triangle with the side lengths 2,5,7 could be a triangle because 2+5 is equal to 7. even if the longest side was 6 units long it would still be a triangle. in this situation though the side lengths are 3,4,9. 3+4=7 and 7<9. this is not a triangle.
