The temperature has been rising X degrees per day for X days.
That means it rises, x*x or x^2 degrees in x days
:
X days ago it was 15 degree. today it is 51 degree
51 - 15 = x^2
x^2 = 36
x = sqrt%2836%29
x = 6 days, or 6 degrees/day
:
how much has the temperature been rising each day?
6 degrees
:
how many days has it been rising ?
6 days

If the temperature has been rising x degrees for x days, then the total temperature rise for the x days must be x times x. This total is equal to 51 minus 15 = 36.

So:



Solve for x
