Answer:
Step-by-step explanation:
The easiest way is to use a graphing tool and solve it graphically.
We did it with Desmos and it shows 3 real roots, see below.
The polynomial is of degree 7, hence it should have 7 roots.
Since there are 3 real roots, the remaining ones are complex, so there are 4 complex roots
The plot of land forms right triangle.
Step-by-step explanation:
Let,
the three sides are a,b and c.
The sum of square of two sides equals to the square of third side. We will consider the larger side as c, therefore,
a= 2000 feet
b= 2100 feet
c= 2900 feet
Using Pythagoras theorem;
As the three sides satisfy pythagoras theorem, therefore, the plot of land form right triangle.
The plot of land forms right triangle.
