Let D = {-2 -1. 0. 1. 2}. Is D a subset of itself? Explain.
dolphi86 [110]

Answer:

Yes

Step-by-step explanation:

Given

D = \{-2,-1,0,1,2\}

Required

Is D a subset of itself?

A subset is defined in such a way that, all elements of the subset can be found in the main set.

So; because set D contains all of its elements, then D is a subset of itself.

D = \{-2,-1,0,1,2\}

the length of marshalls retangular poster is 2 times the width if the perimeter is 24 inches what is the area
Ilia_Sergeevich [38]
Let us assume the width of the rectangle = x
Then
The length of the rectangle = 2x
The perimeter of the rectangle = 24 inches
We know the formula of the perimeter of a rectangle is
Perimeter = 2 (length + Breadth)
24 = 2 (2x + x)
24 = 2 * 3x
24 = 6x
x = 24/6
   = 4
So the width of the rectangle = 4 inches
length of the rectangle = 2x
                                     = 2 * 4 inches
                                     = 8 inches
Now 
The Area of the rectangle = Width * Length
                                          = 4 * 8 inches^2
                                          = 32 inches ^2
So the area of the rectangle is 32 square inches. I hope i have helped you.
