Step-by-step explanation:
The required result is 
a)

b)

c)

d)

IN ORDER TO FIND THE ANSWER:
Add up two of the values. If they are greater than the third, the lengths can make up a triangle.
3 + 9 = 12
12 > 14? No
3 + 5 = 8
8 > 7? Yes
1 + 2 = 3
3 > 3? No
4 + 4 = 8
8 > 8? No
The answer would be B.
Look at it this way:
g=2
H=7
so it would be 2*5-7*3
than just do the multiplication first so 2*5=10 and 7*3=21 than subtract the two 10-21=-11
