You would need 6ft of carpet.
Answer:
Step-by-step explanation:
d-4=19d=15
We move all terms to the left:
d-4-(19d)=0
We add all the numbers together, and all the variables
-18d-4=0
We move all terms containing d to the left, all other terms to the right
-18d=4
d=4/-18
d=-2/9

Aimee is shipping a care package to her friend in college, the max volume of the box is mathematically given as
V=1539.6007
<h3>What is the max
volume of the box?</h3>
Generally, the equation for the height is mathematically given as
V=(20-2x)(40-2x)x
Where x is the height
V=4x^3-120x^2+800x
differentiate v and solve
dv/dx=3x^2-60+200
3x^2-60+200=0
Therefore
x=![\frac{60\pm \sqrt{60^2-4x3x200}}{2*3}](https://tex.z-dn.net/?f=%5Cfrac%7B60%5Cpm%20%5Csqrt%7B60%5E2-4x3x200%7D%7D%7B2%2A3%7D)
x=![\frac{60-34.64}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B60-34.64%7D%7B6%7D)
x=4.2265
In conclusion, the second differentiation of v and solve we have
d^2v/dx^2=24-240
Hence
d^2v/dx^2< 0
V=(20-2x(40-2x)x
subsitute x
V=(20-2(4.2265))(40-2(4.2265))(4.2265)
V=1539.6007
