The population of a local species of dragonfly can be found using an infinite geometric series where a1=42 and the common ratio

san4es73 [151]

$\bf \textit{sum of an infinite geometric serie}\\\\
\stackrel{for~~|r|\ \textless \ 1}{S=\sum\limits_{i=0}^{\infty}~a_1r^i\implies \cfrac{a_1}{1-r}}\qquad 
\begin{cases}
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
a_1=42\\
r=\frac{3}{4}
\end{cases}
\\\\\\
S=\cfrac{42}{1-\frac{3}{4}}\implies S=\cfrac{42}{\frac{1}{4}}\implies S=164$

bearing in mind that, the geometric sequence is "convergent" only when |r|<1, or namely "r" is a fraction between 0 and 1.

The length of a rectangle is 3 less than 2 times the width if the perimeter is 60 what is the length

Semenov [28]

P=2w+(2w-3)
60=4w-3
63=4w
15.75=w

l=2w-3
l=(2×15.75)-3
l=31.5-3
l=28.5

This answer doesn't add up so if you meant the COMBINED width then:

P=w+(2w-3)
60=3w-3
63=3w
21=w

l=2(21)-3
l=42-3
l=39

(This answer checks out so this is probably what you meant hope I helped)
