a rectangular area of land is being sold off in smaller pieces. The total area of land is 215 square miles. The pieces being sold are 83 square miles in size. How many smaller pieces of land can be sold at the stated size

a² + b²= c²

24² + 7² = c²

c= 25

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
