Here's the gist and you can then elaborate:

Proof: 
BC = EC, AC = DC (this is given)
angle BCA = angle ECD (vertical angles)
Therefore  triangle BCA = triangle ECD (by the side-angle-side theorem).
So therefore BA = ED ( by Congruent Parts of Congruent Triangles are Congruent)

This is not a paragraph proof. You will need to add a little bit more of explanation.

Because all outcomes are equally weighted, the probability you are looking for is given by :-
Number of favorable eventsTotal number of events
Number of favorable events
Total number of events

In your case: 6 or Even outcome={2,4,6}
6
or Even outcome
=
{
2
,
4
,
6
}
and Outcomes={1,2,3,4,5,6}
Outcomes
=
{
1
,
2
,
3
,
4
,
5
,
6
}

Hence:

21. You are making a rectangular poster to advertise a school fundraiser. You
liubo4ka [24]

The simplified expression for perimeter is 6w, and for area is 2w². 3 meters of a width will allow the most area while not exceeding a perimeter of 20 meters.

Step-by-step explanation:

Let w represent the width of the poster then,

The length of the poster is twice as long as its width, to mean the length is 2w

Perimeter is the distance around the figure. Your figure is a rectangle with sides width, w and length 2w;

Perimeter formula is = 2(l+w) where l is length and w is with

P=2(2w+w) = 2(3w) = 6w meters

Area is given by the product of length and width of the figure

Area=l*w

A=2w*w= 2w²

The table will be;

<u>Width in (m)       Perimeter=6w in (m)           Area (2w²) in m²</u>

3                          6*3= 18                                   2*3²=2*9=18

4                          6*4=24                                  2*4²=2*16=32

Width 3 allows for the most area while not exceeding a perimeter of 20 meters.
