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.

Answer:

Step-by-step explanation:

1) Take the natural log of both sides, obtaining:

-0.20x + ln 3.80 = ln 2

2) Group the ln terms on the right side: -0.20x = ln 2 - ln 3.80

3) Find the natural logs of 2 and 3.80 and combine them: -0.408, so that we have 0.20x = 0.408.

4) Solving for x, we get 2.03, or approx 2 (Answer C)
