Answer:
<h2><u><em>
P = 16</em></u></h2><h2><u><em>
C = 24-P = 8</em></u></h2>
Step-by-step explanation:
Heads: P + C = 24
C = 24 - P
Legs: 4P + 2C = 80
Substitute, from heads: 4P + 2 (24 - P) = 80
4P + 48 - 2P = 80
2P = 32
<u><em>P = 16</em></u>
<u><em></em></u>
<u><em>C = 24-P = 8</em></u>
====================
Check:
P + C = 16 + 8 = 24
4P + 2C = 4(16) + 2(8) = 64 + 16 = 80
The answer is 41
All u do is divide 205 by 5 which will equal 41
The corner is 60°, and based on the information given it is D...but if you can measure the angle, it would be B... A and C assume different sizes.

Step-by-step explanation:
We want to the equation in an exact form
M(x, y) dx + N(x, y) dy = 0.
xy² dy/dx = y³− x³
Cross multiply
Then,
xy²dy=(y³-x³)dx
xy²dy - (y³-x³)dx = 0
xy²dy + (x³-y³)dx=0
Therefore,
(x³-y³)dx + xy²dy=0
Can only be an exact equation if and only if
dM/dy=dN/dx
From the equation
M=(x³-y³)
Then, dM/dy=-3y²
Also, N=xy²
dN/dx=y²
Since dM/dy ≠ dN/dx
Then it is not an examct equation and we can say
M≠(x³-y³)
And
N≠(xy²)
