Answer:
<h2>52 ft.</h2>
Step-by-step explanation:
In this case, we need to calculate a perimeter, which is the sum of all sides of the rectangle.
So, rectangles has opposite sides equal, therefore, the perimeter should be:
; having L as the larger side.

Hence, the strip of wallpaper needs to be as least 52 ft.

Answer:
2x - 2 = 14
Step-by-step explanation:
Let x be the amount of hats Fran has, if Elena has -2 hats, then this can be shown by x - 2
So then
x + x - 2 = 14
2x - 2 = 14
You haven't asked this but to find the amount of hats they have, move the -2 over to the other side making it a +2:
2x = 14 + 2
2x = 16
x = 8
So Fran has 8 hats and Elena has 6 hats.

OK, so;
BDE and BED are congruent because the opposite sides are both congruent
To find BDE and BED you must subtract 66 degrees from 180 degrees.
You are then left with 114 as the sum of both the angles you need to find
Since they are congruent, all you need to do is divide by two
114/2=57 degrees for both BDE (a) and BED(b)
Now for angle A and C;
This is easy because they are both congruent to the first two!
So basically, all of question four is "57 degrees"
Sadly for number 5 i did not understand the question :"(
For 6 tho;
AC is parallel to DE because angle C is congruent to angle BED
All the others can be ruled out
For 7;
BD is half the length of AE, so:
4x+20=2(3x+5)
4x+20=6x+10
20=2x+10
10=2x
x=5
This means BD is 20 bc
3(5)+5
15+5
20
And AE is 40 bc
20X2=40
or...
4(5)+20
