Answer:
Area = x^2+4x+3
Step-by-step explanation:
The volume of a box is given by the expression
x^3 + 3x^2 - x-3. The height of the box is given by the expression x-1.
volume of the box = Length * width * height
L is the side length of the box;
Given
V(x) = x^3 + 3x^2 - x-3
Factorize
V(x) = x^2(x+3)-1(x+3)
V(x) = (x^2-1)(x+3)
V(x) = (x+1)(x-1)(x+3)
V = LWH
V = Area * Width
Since the height of the box is x - 1
Area = (x+1)(x+3)
Expand
Area = x^2+3x+x+3
Area = x^2+4x+3
And ruler because it has the specific measurements on it
We substitute m=9 in a=28500-1800m
a = 28500 - 1800(9) = 28500 - 16200 = 12300
Answer: 12,300 feet
Positive is when the lines are above the X axis
in this graph it is positive from [−8, −6) and (−2, 4)
