PLEASE HELP Write an expression in terms of x that could be used to determine the surface area of a cube with a side length of x inches.​

The variable z is directly proportional to x, and inversely proportional to y. when x is 4 and y is 13, z has the value 1.2307692307692. what is the value of z when x= 9, and y= 20

Atransformation t : (x,y) (x-5,y +3) the image of a(2,-1) is
