48 and 6/8 that is the answer
EF = 50 in.
In similar figures, corresponding sides are proportional. We use the similarity statement ABCD~EFGH to write a proportion:

Cross multiply the proportion:
45*x = 75*30
45x = 2250
Divide both sides by 45:
45x/45 = 2250/45
x = 50
5(x+3)=7x-3 which is the equation, then we solve for it, and the answer is 9
