please make it easy for me to understand properly thanks

Of all points (x,y,z) that satisfy x + 5y + 2z =18, find the one that minimizes (x - 1)2 + (y - 1)2 + (z- 1)2. . . . The given function has a minimum at which satisfies x + 5y + 2z = 18. (Simplify your answer.)Find the extremum of f(x,y) subject to the given constraint, and state whether it is a maximum or a minimum. f(x.y)=ax2+y2w;x+y=2o There is a value of D located at (x, y) = Cl. (Simplify y( maximum minimum Find the extremum of f(x,y) subject to the given constraint, and state whether it is a maximum or a minimum. f(x,y) = xy; 10x + y = 4 . . . Find the Lagrange function F(x,y,a). F(x,y,2) = - Find the partial derivatives F , Fv, and Fx. Fx F, = There is a value of located at (x,y) = (Type an integer or a fraction.
