Answer:

Step-by-step explanation:
To find this derivative, we will need to use the chain rule.
As there is a variable in the exponent we can use this formula:

In this case,
and 
This means that
and
respectively
This gives us 
The formula for perimeter is
Side a x2 + side b x2
So just multiply 18 by two, and subtract it from 108
Answer:88
Step-by-step explanation:
the equation of a line in point-slope form is
y - b = m(x - a)
where m is the slope and (a, b ) is a point on the line
y + 1 =
(x + 5) is in this form
(a) with slope = 
(b) point on the line = (- 5, - 1 ) = (a, b)
