Step-by-step explanation:
<u>Given</u>
- Initial price = $25
- Sale price = $21.25
<u>Discount </u>
<u>Discount %</u>
-32+<u>50</u> =2(x^2+10x+25)
18=2(x+5)^2
9= (x+5)^2
+-<u /> <u>3</u> = x+5
x= -2 or x= <u>-8</u>

Take 126/399 and divide it by 3. then you get 42/133. There is no other numbers that divide equally into the numbers, so you are done.
Volume = Pi × radius squared × height
Radius = Diameter ÷ 2
= 8 ÷ 2
= 4 cm
Volume = Pi × 4 squared × 12
= Pi × 16 × 12
= 603.1857895...
= 603.19 cm cubed
Note : Pi is approximately equal to 3.14
