The perimeter of a square box is 12x+32. write an equivalent expression that shows the perimeter as four times the side length of the box.

The perimeter of a square is the sum of each of its four sides. If each side is :

Which is the same as:

   (1)

In this case we are told that the perimeter of a square box is:

   (2)

Or:

   (3)

If we want to find the equivalent expression as it was asked, we firstly have to find the value of one side from (3):

   (4)

Simplifying by the common factor:

   (4)

>>>>>This is the value of each side of the square box

Now, equivalent expression that shows the perimeter as four times the side length of the square box, is four times :

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.
