4 0

Answer:

First you should see that the 2s cancel out. The equation becomes:

ln( e^{ln(5x)} ) = ln15ln(e

ln(5x)

)=ln15

Use the laws of logarithms, knowing that ln(e) = 1.

\begin{gathered}ln(5x) = ln(15) \\ 5x = 15 \\ x = 3\end{gathered}

ln(5x)=ln(15)

5x=15

x=3

The answer is B.

Hopefully this helps!

Step-by-step explanation:

x=3

Step-by-step explanation:

Given in an equation as

2 ln e^ln5x=2 ln 152lne

l

n5x=2ln15

Divide 2 to get

ln e^ln5x= ln 15lne

l

n5x=ln15

Using log rules for exponents we get

ln 5x = ln 15

Cancel ln to get

5x=15x=35x=15x=3

Hence solutin is x=3

Verizon [17]
The answer is:  "40 cm " .
_________________________________________________________
<u>Note</u>:
_________________________________________________________

\frac{200 ft }{ (x) cm} = \frac{5}{1}  ;

Solve for "x" (in "cm" ) ; 


→  5x = 200 * 1 ; 

→  5x = 200 ; 

Divide each side of the equation by "5" ; 
   to isolate "x" on one side of the equation; & to solve for "x" ; 

→  5x / 5 = 200 / 5 ; 

to get:

→  x = 40 .

What is another way to write the expression t. (14--5) ?
melomori [17]

Answer: Second option.

Step-by-step explanation:

It is important to remember the Distributive Property in order to solve this exercise.

The Distributive property states that:

a(b+c)=ab+ac\\\\\\a(b-c)=ab-ac

In this case you have the following expression provided in the exercise:

t(14-5)

Then, in order to write this expression in another way, you can apply the Distributive property. Multiply each number inside the parentheses by "t".

Applying this procedure, you get:

t(14-5)=(t14)-(t5)

Notice that this expression matches with the one shown in the the second option.
