Answer: Choice C)

(x-2)(3x) + (x-2)(4)

======================================

How to get this answer? One easy way that might work is to let y = x-2, which will allow us to do a replacement.

We will go from (x-2)(3x+4) to y(3x+4). Now use the distributive property to multiply the y term by each term inside

y(3x+4) = y*3x + y*4 = (y)*(3x) + (y)*(4)

The last step is to re-introduce y = x-2 back in. So replace y with x-2 like so

(y)*(3x) + (y)*(4) = (x-2)*(3x) + (x-2)(4)

Write an equation for an exponential growth function where the initial population is 74 and the population quadruples during eac

Liono4ka [1.6K]

If the population quadruples every period say hour, that means the "rate of growth" is 300%, so whatever the current amount, increased by 3 times as much is 4 times the current amount, or a quadrupled amount.

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &74\\
r=rate\to 300\%\to \frac{300}{100}\to &3.00\\
t=\textit{elapsed time}\\
\end{cases}
\\\\\\
A=74(1+3)^t\implies A=74(4)^t$
