Answer:
Base area of box = ![x^2 +4](https://tex.z-dn.net/?f=x%5E2%20%2B4)
Step-by-step explanation:
![Length = 4+x](https://tex.z-dn.net/?f=Length%20%3D%204%2Bx)
![Height = x^2 + 1](https://tex.z-dn.net/?f=Height%20%3D%20x%5E2%20%2B%201)
Base area of a rectangular box is a rectangle
Area of a rectangle (base area)= length times width
![Length = 4+x](https://tex.z-dn.net/?f=Length%20%3D%204%2Bx)
![Width = x](https://tex.z-dn.net/?f=Width%20%3D%20x)
Base area = ![(4+x) \cdot x](https://tex.z-dn.net/?f=%284%2Bx%29%20%5Ccdot%20x)
Multiply x inside the parenthesis
Base area of box = ![4x +x^2](https://tex.z-dn.net/?f=4x%20%2Bx%5E2)
Slope intercept form is y = mx + b.
Y = coordinate y.
M = Slope
X = coordinate x.
B = y-intercept.
Slope formula: (y2-y1) / (x2-x1)
Plug in: (-1 - 7) / (4 - 2) = -4.
We can just insert the pair (2,7) as our x and y to solve b.
7 = -4(2) + b.
Solve for b.
7 = -8 + b.
-b = -8 -7
-b = -15
b = 15.
Original equation:
y = mx + b
y = -4x + 15
Answer:
![profit \: percent = \frac{sp - cp}{cp} \times 100 \: percent](https://tex.z-dn.net/?f=profit%20%5C%3A%20percent%20%3D%20%20%5Cfrac%7Bsp%20-%20cp%7D%7Bcp%7D%20%20%5Ctimes%20100%20%5C%3A%20percent)
where,
SP=Selling price
CP=Cost price
<h3>
For example:</h3>
Given,
Selling price(SP)= 1000
Cost price(CP)=800
Now,
![profit \: percent = \frac{sp - cp}{cp} \times 100 \: percent \\ = \frac{1000 - 800}{800} \times 100 \\ = \frac{200}{800} \times 100 \\ = 25 \: percent](https://tex.z-dn.net/?f=profit%20%5C%3A%20percent%20%3D%20%20%5Cfrac%7Bsp%20-%20cp%7D%7Bcp%7D%20%20%5Ctimes%20100%20%5C%3A%20percent%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1000%20-%20800%7D%7B800%7D%20%20%5Ctimes%20100%20%5C%5C%20%20%3D%20%20%5Cfrac%7B200%7D%7B800%7D%20%20%5Ctimes%20100%20%5C%5C%20%20%3D%2025%20%5C%3A%20percent)
