4) A flower-bed is in the shape of a triangle with one side twice the length of the shortest side and the third side 15 feet longer than the
shortest side. If the perimeter is 100 feet, what is the length of all 3
sides?

the answer is b.)

< 1=< 2

answer: about 22.67

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

2  

x

=240

=48
