Step-by-step explanation:
I'm not sure what you mean by 'written method' but the sum is 2,654.

By the fundamental theorem of calculus,

Now the arc length over an arbitrary interval

is

But before we compute the integral, first we need to make sure the integrand exists over it.

is undefined if

, so we assume

and for convenience that

. Then
Answer:
15 + x = 38
KEY:
<u>Increased = addition</u>
is= equals to
a number = put any random letter, or my choice is just using "x" so its just means a varaible
