Any side that is greater than 7 + 7 = 14 will not make a triangle.
x > 14 will not create a triangle.
For every 3 girls, there are 4 boys. if there are nine girls, that expands to three extra boys, because for every three theres an extra one. so there are 12 boys (9+3.) the final ratio, boys to girls, is 12:9.
