22. Use the information from Question 21. Show how the Distributive Property can be used to find the area of Marlene's living room. 23 Use the algebraic expression for length and width of Marlene's living room found in the diagram and the value of x found in Question 21C

A. find the actual length and width of her living room.

B. Find the actual area of Marlene's living room use actual dimensions.

420 feet

Step-by-step explanation:

x=14, so you plug in 14 for x*(x+2)

the first option is the answer.

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
