We will solve for
x
using the very basic properties of natural logarithms. I'll illustrate it below.
Explanation:
We have,
ln
(
x
−
2
)
2
=
6
Using the property,
ln
m
n
=
n
ln
m
,
We have,
ln
(
x
−
2
)
2
=
6
⇒
2
ln
(
x
−
2
)
=
6
⇒
ln
(
x
−
2
)
=
3
⇒
x
−
2
=
e
3
In the last step, we used the concept of inverse of the natural logarithms,
ln
m
=
n
⇒
m
=
e
n
Thus,
x
=
e
3
+
2
Where e is the base of natural logarithms.

Dimensions of walkway and pool= (23+3) x (32+3) => 26ft x 35 ft
Perimeter: 2(l+w)
= 2 (26ft + 35ft)
= 122 ft fence would be required to enclose the walkway and the pool.
D.y = 10x + 250
y = 12x + 150 is the correct answer to the question
