In inches, what is the perimeter of a rectangle with a width of 4 inches and length of 10 inches?

The perimeter is the distance around the object so you add 4+10+4+10 to get
28 inches as the perimeter of the rectangle

The perimeter of a shape is all of the sides added up.

On a rectangle there are 2 short sides(width) and two longs sides (length)

The width is 4
The length is 10

10+10=20
4+4=8
20+8=28

The perimeter of the rectangle is 28inches

The population of bacteria can be expressed as a function of number of days.

Population = where n is the number of days since the beginning.

Step-by-step explanation:

Number of bacteria on the first day=

Number of bacteria on the second day =

Number of bacteria on the third day =

Number of bacteria on the fourth day =

As we can see , the number of bacteria on any given day is a function of the number of days n.

This expression can be expressed generally as where n is the number of days since the beginning.
