The length of a rectangle is 4 less than 3 times the width. if the perimeter is 40, find the dimensions of the rectangle.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3

where is the graph? need more info
