4. ### help with inverse laplace transform (s^2)/((s+2)^4)?!?!?!?

s^2/(s+2)^4 = [(s+2) - 2]^2 / (s+2)^4 = ((s+2)^2 - 4(s+2) + 4) / (s+2)^4 = 1/(s+2)^2 - 4/(s+2)^3 + 4/(s+2)^4. (Alternately, use partial fractions to obtain this.) Inverting term by term: te^(-2t) - 4(t^2/2!)e^(-2t...

6. ### what does not represent a rectangle with lengths s+4, width s+8, and area of 75?

Length = s plus 4, breadth = s plus 8. So,area = (s plus 4)*(s plus 8) = s^2 plus 12s plus 32. Now,this one equals to 75. Now, A. (s 4)(s 8)-75=0 It represents the rectangle.Because, ...
