Answer: -2w^2 + 25w = 25 or -2w^2 + 25w - 25 = 0</h3>
================================================================
Explanation:
Refer to the diagram below. The width is w. We have two opposite and parallel sides equal to this. The other two parallel congruent sides are L = 25-2w meters long. We start with the total amount of fencing, and then subtract off the two width values, so 25-w-w = 25-2w.
The area of the rectangle is
Area = length*width
Area = L*W
Area = (25-2w)*w
Area = 25w - 2w^2
Area = -2w^2 + 25w
Set this equal to the desired area (25 square meters) to get
-2w^2 + 25w = 25
and we can subtract 25 from both sides to get everything on one side
-2w^2 + 25w - 25 = 0
side note: The two approximate solutions of this equation are w = 1.0961 and w = 11.4039 (use the quadratic formula or a graphing calculator to find this)
When x=2 y = 110 which means when when x=1 y = 55
the graph would be 11*55 or 605
The table would be 280/4= 70 70*11=770
Which means the difference is 770-605=165
165 is ur answer

Answer:
38 quarters
Step-by-step explanation:
0.25 x 63 = 15.75
0.05 x 63 = 3.15
----------------------------
0.25 x 50 = 12.50
+ = $13.15
0.05 x 13 = 0.65
----------------------------
0.25 x 25 = 6.25
+ = $8.15
0.05 x 38 = 1.90
----------------------------
0.25 x 30 = 7.50
+ = $9.15
0.05 x 33 = 1.65
--------------------------
0.25 x 35 = 8.75
+ = $10.15
0.05 x 28 = 1.40
-------------------------
0.25 x 38 = 9.50
+ = $10.75
0.05 x 25 = 1.25
------------------------------
I hope this helps!
