I cant believe how bad my brother, Reuben, is at growing things. He bought a whole bunch of plants at the nursery the other day. Right away, five died. Then our dog dug up 2/9 of them. Then a rabbit came and ate ½ of what was left. Reuben had only seven plants left. How many did he buy at the nursery

68 plants.

Step-by-step explanation:

Let x represent the number of plants that Reuben bought from the nursery.

We have been given that Reuben bought a whole bunch of plants at the nursery the other day. Right away, five died. So number of plant left would be .

We are also told that then our dog dug up 2/9 of them. So number of plants left after dug-up would be .

Further a rabbit came and ate ½ of what was left. So number of plants left would be .

Since Reuben had only 7 plants left, so we will equate our expression with 7 and solve for x as:

Therefore, Reuben bought 68 plants at the nursery.

dude   i don't even know. i've been trying for hours.

step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
