Equation: 
Step-by-step explanation:
By definition, the perimeter of a figure can be calculated by adding the lenghts of its sides.
Knowing this, you can write the following equation:
<em> [Equation 1]</em>
According to the data given in the exercise, the perimeter in feet of the fighter is:

Therefore, you can substitute this values into<em> [Equation 1]:</em>

Finally, you must solve for "x" in order to find its value. This is:

The equation showing the relationship between w and t is 
From the table, we have the following points:
(0,0) and (1,4)
Start by calculating the slope (m)

So, we have:

Simplify the numerator and the denominator

Divide 4 by 1

The equation is then calculated as:

This gives

Simplify

Hence, the equation is

Answer:
29 feet above sea level
Step-by-step explanation:
One floor is 9 feet high, so the top of the first floor will be 9 feet above the ground.
The ground is also 20 feet above sea level, so add 9 to this to find how many feet above sea level the top of the first floor is:
20 + 9
= 29 feet above sea level
