The net below shows the dimensions of Michelle’s living room. She is going to put wallpaper on the living room walls. What is the difference, in square yards, between the total and lateral surface areas of the room?

A = 121.8 yd 2

B= 79.8 yd 2

C= 88.2 yd 2

D= 42 yd2

i think the amount would be $140.62

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
