let the unknown side be x , so we have :
25^2 = 20^2 + x^2
625 = 400 + x^2
x^2 = 625 - 400
x^2 = 225
x = √225
x = 15
It means your solving for x
Answer:

Step-by-step explanation:
If we are to write an equation of the form
, then the function is linear; therefore, it has a constant slope
.
The slope
of the function is given by


thus we have

Now we find
from the fact that the first month of service costs $72.99, which gives us
, or


Substituting the values of
and
, we get our equation in the final form:

7 lies betwee the 2 square integers 16 and 25.
