Answer:
-5/2
Step-by-step explanation:
log (2z) = log(6z+10)
When you have a single logarithm or ln in both sides of the ecuation, delete them
2z=6z+10
2z-6z=10
-4z=10
z=10 / -4
z= -5/2
Z= 23/35 Hope this helps :)

----------------------------------------
Define x:
----------------------------------------
Let x be the length of the pool.
Length of the pool and its border = x + 1 + 1
Length of the pool and its border = x + 2
----------------------------------------
Given area = 361 ft², find x:
----------------------------------------
(x+2)² = 361
x+ 2 = √361
x + 2 = 19
x = 19 - 2
x = 17
----------------------------------------
Find Length of the pool:
----------------------------------------
Length of the pool = x = 17 feet
----------------------------------------
Find Area of the pool:
----------------------------------------
Area = 17 x 17
Area = 289 ft²
------------------------------------------------------------
Answer: Area of the pool = 289 ft²
------------------------------------------------------------
