PLS HELP: Perimeter: (x – 4) + (x + 1) + (x + 5) = x+2 - Equation: 2x +2 = 20 In the example, explain how the term 9/4x ( fraction) was obtained in the expression for the perimeter.

it is x equals 3   plese mark me really need it

step-by-step explanation:

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

x

​    

=240

=48
