I've worked this out a bunch of times and I keep getting an answer that's not listed. Please help! I'll give 25 points!

The marriott family bought a new apartment three years ago for $65,000. the apartment is now worth $86,515. assuming a steady rate of growth, what was the yearly rate of appreciation? what is the percent of the yearly rate of appreciation?

Sanya noticed that the temperature was falling at a steady rate of 1.4 degrees every hour from the time that she first checked her outdoor thermometer. by 6 a.m., the temperature had fallen 21 degrees. which expression can you use to find how many hours earlier she had first checked the thermometer?

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9
