Answer:
76 feet
Step-by-step explanation:
Area of Dog Run = 240
Length of Dog Run = 30
Width of Dog Run = 30 - x
Area of Dog Run: 30 * (30 - x) = 240
240 / 30 = 30 - x
8 = 30 - x
x = 24
Width of Dog Run = 8
How many feet of fencing will George need for the dog run?
Perimeter of Dog Run = 2Length + 2Width
Perimeter of Dog Run = (2 * 30) + (2 * 8)
Perimeter of Dog Run = 60 + 16
Perimeter of Dog Run = 76
Answer:
The volume of the box is
V(x) = 4x^3 -72x^2+320x
Step-by-step explanation:
Here, we are interested in calculating the volume of the box
From what we can see, the shape of the box is a cuboid
Mathematically, the volume of a cuboid is l * b * h
Thus, what we have will be;
x * 20-2x * 16-2x
= x ( 20(16-2x) -2x(16-2x))
= x(320-40x-32x + 4x ^2)
= x(320-72x+4x^2)
= 320x-72x^2 + 4x^3
the volume v(x) will be;
V(x) = 4x^3 -72x^2+320x
