Which of the following is the solution of 5e2x - 4 = 11?

x = (1/2)(ln 3)

Step-by-step explanation:

Please indicate exponentiation using the symbol " ^ ":

5e^(2x) - 4 = 11

To solve this, add 4 to both sides, obtaining:   5e^(2x) = 15

Next, divide both sides by 5, obtaining                e^(2x) = 3

Now take the natural logarithm (ln) of both sides:

2x = ln 3

Finally, divide both sides by 2, obtaining:           x = (1/2)(ln 3)

This last result is approx. equal to 0.549

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
