Answer:
r= 8
Step-by-step explanation:
Devide both sides by -4
Length = 31 ft
width = 19 ft
Assume that the width of the rectangle is w.
We are given that the length is 12 ft more than the width. This means that the length of the rectangle is w + 12
The perimeter of the rectangle in this case would be:
perimeter = 2 (length + width)
perimeter = 2 (12 + w + w)
perimeter = 24 + 4w
Assume that Dan would use all 100 ft of fencing to surround the yard. This would mean that the largest perimeter is 100 ft.
Therefore:
perimeter = 24 + 4w
100 = 24 + 4w
4w = 100 - 24
4w = 76
w = 19 ft
Since we have calculated that the width of the yard is 19 ft, we can substitute to get the length as follows:
length = 12 + w
length = 12 + 19
length = 31 ft

Answer:
900 degrees
Step-by-step explanation:
This question is asking you to figure out what all the angles in the shape add up to. There is actually a formula for this: a function of the number of sides that a polygon has.
> Memorize this formula if you will need to do these kinds of problems for your tests/quizzes!
(n - 2) * 180
Since this polygon has 7 sides, we substitute n = 7 into the formula, and solve.
(7 - 2) * 180
5 * 180 = 900
The sum of the interior angles of the polygon shown is 900 degrees.
