A.) An equilateral triangle has three lines of symmetry. It has rotational symmetry of order 3. It has three equal sides.
b.) A Square (4 sides) has 4 Lines of Symmetry.
c.) A Regular Hexagon (6 sides) has 6 Lines of Symmetry
The roots of an equation are simply the x-intercepts of the equation.
See below for the proof that
has at least two real roots
The equation is given as: ![\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Cfrac%7Bx%5E4%7D%7B2021%7D%20%3D%202021x%5E2%20-%20x%20-%203%20%3D%200%7D)
There are several ways to show that an equation has real roots, one of these ways is by using graphs.
See attachment for the graph of ![\mathbf{\frac{x^4}{2021} = 2021x^2 - x - 3 = 0}](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Cfrac%7Bx%5E4%7D%7B2021%7D%20%3D%202021x%5E2%20-%20x%20-%203%20%3D%200%7D)
Next, we count the x-intercepts of the graph (i.e. the points where the equation crosses the x-axis)
From the attached graph, we can see that
crosses the x-axis at approximately <em>-2000 and 2000 </em>between the domain -2500 and 2500
This means that
has at least two real roots
