False, because a^2+b^2=c^2 and no matter what numbers substitute for which ever variable the answer isn’t going to be true
Then, it would be: An = a
this circle is made up of 12 parts
12 to 1 is 1/12
12 to 2 is 2/12
12 to 3 is 3/12
12 to 4 is 4/12 which is 1/3 simplified
or, 4 is 20 minutes, there are 60 minutes in the circle
20/60 = 2/6=1/3

Answer:
n = 59
Step-by-step explanation:
I find it easiest to work problems of this kind using a graphing calculator. That way, extraneous solutions can be avoided. It seems to work well to rewrite the problem, so you're looking for a value of n that makes the result zero. Here, that would mean you want ...
... f(n) = √(n+5) -√(n-10) -1
_____
The solution by hand involves eliminating the root symbols. You do that by squaring the equation:
... n +5 -2√((n+5)(n-10)) + n -10 = 1
Now, we isolate the remaining root and square again.
... 2n -6 = 2√((n+5)(n-10)) . . . collect terms, add 2√( ) -1
... n -3 = √(n²-5n-50) . . . . . . . divide by 2
... n² -6n +9 = n² -5n -50 . . . . square both sides
... 59 = n . . . . . . . . . . . . . . . . . add 50 +6n -n²
