Answer:
length is 60 and width is 30
Step-by-step explanation:
because the formula to find perimeter is 2l+2w and if you plug 60 and 30 into that equation then you get 120+60 which is 180
Answer: transforms
Step-by-step explanation:
Multiplying both sides by
gives

so that substituting
and hence
gives the linear ODE,

Now multiply both sides by
to get

so that the left side condenses into the derivative of a product.
![\dfrac{\mathrm d}{\mathrm dx}[x^3v]=3x^2](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cmathrm%20d%7D%7B%5Cmathrm%20dx%7D%5Bx%5E3v%5D%3D3x%5E2)
Integrate both sides, then solve for
, then for
:
