One side of a rectangle is 5 millimeters shorter than five times the other side. find the length of the longer side if we also know that the perimeter of the rectangle is 158 millimeters.

Use the function nest to evaluate p(x) = 1 + x + · · · + x50 at x = 1.00001. (use the matlab ones command to save typing.) find the error of the computation by comparing with the equivalent expression q(x) = (x51 − 1)/(x − 1).

Given f(x)= 9x+1 and g(x)=x^3, choose the expression (f*g)(x)
