I need quickly answer pls

x = -3, x=0 extraneous

Step-by-step explanation:

The first and third options are ruled out because if you substitue zero for x into the equation you get 3/0,which is not possible.

The only two options remaining are x= 3 or x=-3.If you substitute both for x ,you will find x=-3 to be the solution.

3/-3 = [4(-3) +3]/3^2

-1 = [-12 +3]/9

-1 = [-9]/9

-1=-1 so this is true and therefore it's the solution

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
