my best guess is (-1,1) (-1,2) (-2,3), i just drew a line graph and plotted the points and connected where the x axis lines meet
Considering the perimeter concept, we have that:
- Danielle's mistake is that she did not consider two outside edges, one of length 6x - 4 and the other of length 12x + 3.
- The correct perimeter, in feet, is: P = 50x + 27.
<h3>What is the perimeter of a polygon?</h3>
The perimeter of a polygon is given by the sum of all the lengths of the outside edges of the polygon.
For this problem, the outside edges are given as follows:
- 2 of 6x - 4, due to the isosceles triangle.
- 2 of 12x + 3, due to the rectangle.
- 1 of 14x + 13, also due to the rectangle, and only one, because of the other part of the rectangle with the same length is internal to the prism;
Danielle's mistake is that she did not consider two outside edges, one of length 6x - 4 and the other of length 12x + 3. Considering all the edges, the perimeter is given by:
P = 2(6x - 4) + 2(12x + 3) + 14x + 13
P = 12x - 8 + 24x + 6 + 14x + 13
P = 12x + 24x + 14x + 8 + 6 + 13
P = 50x + 27.

Let quarters = q and
Dimes = d
We have 741 coins total so q + d = 741
Since quarters are 25 cents and Dimes are 10 cents then
25q + 10d = 10725 cents
Now we have 2 equations that we can solve using addition or substitution.
Using addition, first multiply the first equation by -10
-10 (q+d) = 741 (-10)
-10q - 10d = -7410
Now add the equations together
(-10q -10d = -7410)
+ (25q + 10d =10725)
________________
15q = 3315
q = 3315 / 15
q = 221
this is the number of quarters
Now plug this back into the original equation
q + d = 741
221 + d = 741
d = 741 - 221
d = 520
There are 520 dimes
