Answer:
127
Step-by-step explanation:
400+1495=1895
1895/15=126.333333333
A) 122 in^2, this is because 3 x 7 x 2= 42, 4 x 7 x 2= 56, 3 x 4 x 2= 24, once you add up all the sums it equals 122
B 2/10 is not simplified because you can divide each number by 2 reducing it to 1/5.
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
Answer: it is 15
