How many 1-ft square tiles would it take to cover the floor of a square room that is 26 ft on each side?

104

Step-by-step explanation:

Well if there 4 sides you do 26x4 =104. Then if you do 104x1=104.

just sum

10 + 10 = 20

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
