~~~~~~~~~~~~~~~~

Are my corrections right ?


Do you agree with them ??


--------------
 = 44.83


 = 2025.


The father will be 45 years old in 2025.

Hence, his year of birth is 1980.

In 2010 the father was 30 years old.

In 2017 the father is (or will be) 37 years old.


This is the only reasonable sense from the condition and the only reasonable solution.


---------------------
This phrase " . . . i am x years old in the year x²" taken at the given context is the total violence over the English (as I know it . . . ).

sqrt(1900) = 43.5889894354068
sqrt(2000) = 44.7213595499958

44^2 = 1936

So x = 44 and x^2 = 1936

You were 44 years old in 1936

2010-1936 = 74 years pass by from 1936 to 2010

74+44 = 118

So in the year 2010, your age is 118 years. This is on the border of unrealistic (due to average lifespan) but it's possible to live this long. The oldest person lived to about 122 years of age.

Edit: I forgot to adjust to the current year, which is 2017. Adding 7 years to 118 leads to 118+7 = 125 which is over the oldest person on record. So this is even more unlikely.

This problem, like many on algebra.com is just plain STUPID. No wonder most of the kids can never do well in math.

First of all, this convo. occurred in 2010, and so, if it had said, "I told him that I am WAS x years old in the year x²," then he would've been no other age but 44 in the year 1936.

However, if it had said, "I told him that I am WILL BE x years old in the year x²," then he WILL BE 45 in the year 2025. 

This problem says neither so in my opinion, it's DUMB. How can there be a CORRECT answer to this GARBAGE? "I am" denotes the present. 

The age, x, according to the problem, is in the present, but it CANNOT be. It has to be either in the past: 44 years-old, or in the future: 45 years-old.

I welcome some feedback!
