The area of a rectangle is 70 in² and the length of the rectangle is 3 in. longer than the width. the area of a rectangle is found by multiplying the length times the width. during the set up step of the five-step problem-solving plan, which equation would you set up to solve for the width

Step-by-step explanation:

Let w be the width of the rectangle.

We have been given the length of the rectangle is 3 in. longer than the width. So the length of the rectangle would be .

We are also told that the area of a rectangle is 70 in². We know that area of rectangle in length times width. We can represent the given information in an equation as:

Therefore, the equation can be used to find the width 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
