How do I write the algebraic expression representing the perimeter of Marlene’s house in simplest form? (This is the perimeter of the whole house plan: 2x — 10, x — 2, 1/2x—4, x — 2, x — 2, x — 2, 2x + 2, x — 2).

Find a parametrization for the curve「and determine the work done on a particle moving along γ in r3 through the force field f: r^3--r^3'where f(x,y,z) = (1,-x,z) and (a) im (γ) is the line segment from (0,0,0) to (1,2,1) (b) im (γ) is the polygonal curve with successive vertices (1,0,0), (0,1,1), and (2,2,2) (c) im (γ) is the unit circle in the plane z = 1 with center (0,0,1) beginning and ending at (1,0,1), and starting towards (0,1,1)
