The width of a rectangle is 2 less than its length. if the perimeter of the rectangle is no more than30 centimeters, find the range of possible lengths and widths of the rectangle. use the formula, p=2l+2w, for the perimeter of the rectangle. in the form of a paragraph, explain in complete sentences the steps necessary to set up the equation. include the final inequality in your explanation. complete your work in the space provided or upload a file that can display math symbols if your work requires it.

We will take length as variable l and width as variable w.

Formula for perimeter of the rectangle is P=2(l+w)

and l=w+2 and P≤30

First we replace l in formula for perimeter and get this inequality

2(w+2+w)≤30, than we divide this inequlity with 2 and get 2w+2≤15 =>

2w≤13 => w≤6.5

When we replace w in formula for l we get

l-2 ≤ 6.5 => l≤6.5+2 => l≤8.5

If you need some more explenation I am here

good luck!!!

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,
