The right answer is the constant of proportionality
If two variables are related and this relationship is that there is a<em> constant ratio</em> between them, then we are talking about proportionality. There are two types of proportionality.
1) Direct Proportionality:
In a mathematical language this is given by this equation:
where 
is in fact this constant of proportionality. If 
<em>increases,</em> 
also <em>increases</em> at the same rate. On the other hand, If <em> decreases, </em> also <em>decreases</em> at the same rate.
2) Inverse Proportionality:
In a mathematical language this is given by this equation:
where is also called the constant of proportionality. If <em>increases,</em> <em>decreases</em> at the same rate. On the other hand, If <em>decreases,</em> <em>increases</em> at the same rate.

Answer:
24 feet
Step-by-step explanation:
The side adjacent to the angle is given, and the hypotenuse of the triangle is the unknown. The cosine relation applies:
Cos = Adjacent/Hypotenuse
hypotenuse = ladder length = (5 ft)/cos(78°) ≈ 24.0 ft
The ladder is about 24 feet long.

Simplified: 3x2 + 8x +3
In order to determine the difference in size, you must subtract the perimeter of the smaller rectangle from the perimeter of the larger rectangle.</span>
