$3x^2 + 15x + 2x + 10\\(3x^2 + 15x) + (2x + 10)\\3x(x+5) + 2(x+5)\\(3x+2)(x+5)$

18.

$9b^3 + 3b^2 + 24b + 8\\(9b^3 + 3b^2) + (24b + 8)\\3b^2(3b + 1) + 8(3b+ 1)\\(3b^2 + 8)(3b+1)$

Use the fact that the length of an arc intercepted by an angle is proportional to the radius to find the area of the sector give

Hunter-Best [27]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta r^2}{2}~~
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad radians\\
------\\
r=3\\
\theta =\frac{\pi }{4}
\end{cases}\implies A=\cfrac{\frac{\pi }{4}\cdot 3^2}{2}\implies A=\cfrac{\frac{9\pi }{4}}{2}
\\\\\\
A=\cfrac{9\pi }{4}\cdot \cfrac{1}{2}\implies A=\cfrac{9\pi }{8}$

During a promotional weekend, a clothing store gives a $50 gift card to every 75th person who enters the store. On Sunday, there

jeka57 [31]

<h2>Hello!</h2>

The answer is: 34 persons received the $50 gift card.

If we need to know how many many people received a $50 gift card over the two days (Sunday and Monday) we need to divide the total attendance by the number 75 because every 75 persons, there is a $50 gift card.

So, calculating we have:

$TotalAttendance=SundayAttendance+MondayAttendance\\TotalAttendance=1030+1562=2592$

Then, dividing the total attendance by 75 to know how many people received a $50 gift card over the two days, we have:

$ReceivedGiftCards=\frac{2592}{75}=34.6$

Hence, rounding to the nearest whole number, 34 persons received the $50 gift card.

Have a nice day!
