Answer:
<em>p = 14t</em>
Step-by-step explanation:
y = kx
The rate k = 210 ÷ 15 = 14 gel pens per minute
"p" is number of pens, "t" is number of minutes
<em>p = 14t</em>
Answer:

Step-by-step explanation:
5+5=10, so 4+6=10
Area of the entire rectangle ![=x^2+10x+24](https://tex.z-dn.net/?f=%3Dx%5E2%2B10x%2B24)
Solution:
Area of the blue box = length × width
![=x\times x](https://tex.z-dn.net/?f=%3Dx%5Ctimes%20x)
Area of the blue box ![=x^2](https://tex.z-dn.net/?f=%3Dx%5E2)
Area of the pink box = length × width
![=4\times x](https://tex.z-dn.net/?f=%3D4%5Ctimes%20x)
Area of the pink box ![=4x](https://tex.z-dn.net/?f=%3D4x)
Area of the green box = length × width
![=6\times x](https://tex.z-dn.net/?f=%3D6%5Ctimes%20x)
Area of the green box ![=6x](https://tex.z-dn.net/?f=%3D6x)
Area of the orange box = length × width
![=6\times 4](https://tex.z-dn.net/?f=%3D6%5Ctimes%204)
Area of the orange box = 24
Total area of the rectangle ![=x^2+4x+6x+24](https://tex.z-dn.net/?f=%3Dx%5E2%2B4x%2B6x%2B24)
![=x^2+10x+24](https://tex.z-dn.net/?f=%3Dx%5E2%2B10x%2B24)
Area of the entire rectangle
Answer: The first day the author reaches 100 days is on day 16.
To solve this problem, you could use a graphing calculator to graph the given equation. Then, determine when this line crosses 100. It crosses when x = 15.539. Therefore, we would have to round up to 16 so it is at least 100.
You could use the quadratic equation to solve: 100 = x^2 -12x + 45
Either you will get 16. If you use the quadratic formula, make sure to only use the positive answer.
