Completely factor the polynomial below. p^2+19p+60
marissa [1.9K]
The first step for solving this problem is to write 19p as a sum.
p² + 15p + 4p + 60
Factor out p from the expression.
p × (p + 15) + 4p + 60 
Now factor out 4 from the expression.
p × (p + 15) + 4(p + 15)
Lastly,, factor out p + 15 from the expression to find your final answer.
(p + 4) × (p + 15)
This means that the correct answer to your question is (p + 4) × (p + 15),, or option A.
Let me know if you have any further questions.

The new iPhone 3.14 is being sold at the UT Math Department. The original price is $1200 (day 0), but they are going to decrease
Marat540 [252]

\bf \qquad \textit{Amount for Exponential Decay} \\\\ A=P(1 - r)^t\qquad \begin{cases} A=\textit{accumulated amount}\dotfill&50.14\\ P=\textit{initial amount}\dotfill &1200\\ r=rate\to r\%\to \frac{r}{100}\dotfill\\ t=\textit{elapsed time}\dotfill &16\\ \end{cases}


\bf 50.14=1200(1-r)^{16}\implies \cfrac{50.14}{1200}=(1-r)^{16}\implies \sqrt[16]{\cfrac{50.14}{1200}}=1-r \\\\\\ r=1-\sqrt[16]{\cfrac{50.14}{1200}}\implies r\approx 0.18\implies \stackrel{\textit{converting to percent}}{r\approx 0.18\cdot 100}\implies r\approx \stackrel{\%}{18}\quad \leftarrow x
