Answer:
B.) 18
Step-by-step explanation:
To find the correct b value we use this formula
b² - 4ac = 0
b = What we are solving for
a = 1
c = 81
b² - 4(1)(81) = 0
b² - 324 = 0
b² = 324

b = ±18
And 18 is one of the answer choices
So B.) 18 is the correct answer.

Answer:
Not Determinable
Step-by-step explanation:
Simplifying
Ln(4x + 1) = 6
Reorder the terms:
nL(1 + 4x) = 6
(1 * nL + 4x * nL) = 6
(1nL + 4nxL) = 6
Solving
1nL + 4nxL = 6
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Reorder the terms:
-6 + 1nL + 4nxL = 6 + -6
Combine like terms: 6 + -6 = 0
-6 + 1nL + 4nxL = 0
The solution to this equation could not be determined.
