Choice A is one of the answers. Nice work. This is because x+x+x turns into 3x.
Choice D is the other answer because 2(x+1) + x = 2x+2+x = 3x+2. You can find this through trial and error. Or you could graph y = x+x+x+2 and y = 2(x+1)+2 to find that they are the same exact identical diagonal line. A non-graph approach would be to set up a table of values to see that the two tables are identical.

So, we have:
Answer:the number of gallons of water left is 3.5
Step-by-step explanation:
The initial amount of water in the container is 4 3/8 gallons. Converting 4 3/8 gallons to improper fraction, it becomes 35/8 gallons of water.
A hole in the container causes 7/8 gallon to leak out. The number of gallons of water left in the container would be
Initial amount - amount that leaked. It becomes
35/8 - 7/8 = 28/8 = 3 4/8 = 3.5 gallons of water
