Answer:
-2
Step-by-step explanation:
Put the given value in the equation and solve for x.
f(x) = 12
f(x) = 2(x +8)
12 = 2(x +8) . . . . . use 12 for f(x)
6 = x +8 . . . . . . . . divide by 2
-2 = x . . . . . . . . . . subtract 8
Answer:
Length of the box, l = 1.80 inches
Step-by-step explanation:
Let length of the rectangular box is l
Width of the box is 4 times of its length, b = 4 l
Its height is 6 inch more than its length.
Height, h = (6 + l) inch
Volume of the box, ![V=102\ in^3](https://tex.z-dn.net/?f=V%3D102%5C%20in%5E3)
The volume of a box is given by :
![V=l\times b\times h](https://tex.z-dn.net/?f=V%3Dl%5Ctimes%20b%5Ctimes%20h)
![102=l\times 4l\times (6+l)](https://tex.z-dn.net/?f=102%3Dl%5Ctimes%204l%5Ctimes%20%286%2Bl%29)
![4l^3+24l^2-102=0](https://tex.z-dn.net/?f=4l%5E3%2B24l%5E2-102%3D0)
On solving the above equation using online calculator we get,
l = 1.80 inch
