The correct answer is it is a figure with at least 3 straight sides. When you think of a square or a triangle they both have at least 3 sides that are straight. A circle doesn't have any straight sides so it is not a polygon.
You can prove that the other answer is wrong because of two things:
The definition of a polygon is a plane figure with at least three straight sides.
Also, when you think of most shapes what do they all have in common? The have at least three straight sides
Answer:
h = -6
Step-by-step explanation:
Use the quadratic formula

h=\frac{-{\color{#e8710a}{b}} \pm \sqrt{{\color{#e8710a}{b}}^{2}-4{\color{#c92786}{a}}{\color{#129eaf}{c}}}}{2{\color{#c92786}{a}}}
h=2a−b±b2−4ac
Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

Step-by-step explanation:
First piece:
Nathan doesn´t use= 9.8 ft - 5.2 ft=4.6 ft
Second piece:
Nathan doesn´t use=7.5 ft-6.1 ft=1.4 ft
Third piece:
Nathan doesn´t use= 12 ft.
feet of wood don´t use=4.6 ft + 1.4 ft + 12 ft=18 ft.
Answer: Nathan doesn´t use 18 feet
