I believe it is d because they are proportional to each other

Answer:
h=2.2
Step-by-step explanation:
I think you forgot to put the pictures-
In this question, AE is the length of half of one diagonal in the rectangle. DB is the length of the other diagonal. 2(4x-12) would be the total length of the other diagonal, AC. You can set 2(4x-12) equal to 7x-18 and solve for x.
2(4x-12)=7x-18
8x-24=7x-18
x-24=-18
x=6
