Step-by-step explanation:
<em>See the attached.</em>
The path goes along the perimeter of the park and parallel to the sides, something like the picture attached.
<u>The path is 1 m wide and the total length is:</u>
- 50*3 + 30*3 = 240 m
We need to consider the dark cells points in the picture with reflects the overlaps. They are counted twice and each is 1 m x 1 m.
<u>Subtracting the duplicated area 9 x 1 m² to get the total area of the path:</u>
- 240 - 9 = 231 m²
<u>The cost of cementing is:</u>
- 231*20 = 4620
Answer:
Step-by-step explanation:
The first step in solving this equation is the factor, remove a factor that both the quadratic and constant term have in common. In this case, such a term would be (-3),
Now set the equation equal to zero so that one can use the zero product property. The zero product property states that any number times zero equals zero.
Solve, use inverse operations,
One cannot take the square root of a negative number and get a real result, thus the result is an imaginary number.
Simplify, remove whole factors from under the radical,
