Are you supposed to be just simplifying the equation or what? there are like 5 different things to do with this? needs more directions
Saying "4 ft, 2 inches" is the same as saying "4 feet plus 2 inches"
1 foot = 12 inches
4 feet = 48 inches (multiply both sides by 4)
4 feet, 2 inches = 4 ft + 2 in
4 ft, 2 in = 48 in + 2 in
4 ft, 2 in = 50 in
The expression "4 ft, 2 inches" is the same as "50 inches"
-----------
Now we can subtract off 14 inches from this
50 - 14 = 36
We're left with 36 inches which converts to 3 feet because
36/12 = 3
or you can think of it like this
1 ft = 12 in
3 ft = 36 in (multiply both sides by 3)
-----------
<h3>Answer: 3 feet</h3>
Step-by-step explanation:
Lateral Surface Area = 4 X (Side)2
= 4 X (1.8)²
= 4 X 3.24
= 12.96 cm²
∴ The lateral surface area of the net of the cube is 12.96 cm².

Differentiate both sides with respect to 
:
![\dfrac{\mathrm dy}{\mathrm dx}\ln(x^2+y^2+8)+y\dfrac{\frac{\mathrm d}{\mathrm dx}[x^2+y^2+8]}{x^2+y^2+8}=0](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20dy%7D%7B%5Cmathrm%20dx%7D%5Cln%28x%5E2%2By%5E2%2B8%29%2By%5Cdfrac%7B%5Cfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Bx%5E2%2By%5E2%2B8%5D%7D%7Bx%5E2%2By%5E2%2B8%7D%3D0)
We have by the chain rule,
![\dfrac{\mathrm d}{\mathrm dx}[x^2+y^2+8]=2x+2y\dfrac{\mathrm dy}{\mathrm dx}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Bx%5E2%2By%5E2%2B8%5D%3D2x%2B2y%5Cdfrac%7B%5Cmathrm%20dy%7D%7B%5Cmathrm%20dx%7D)
