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
Isolate the variable by dividing each side by factors that don't contain the variable. p=q/2r
(8 - 3i)(2 - 7i)=
16 x -56i - 6i + 21i^2
16 x -50i - 21
When an answer to a question uses the greater than symbol, that means any number above the number used is a possible answer to the equation. However, when it's just a simple "x = 2", then 2 is the only possible answer to that equation. Think about it as if it were on a graph. In the attached file I have a graph that is displaying the equation "x > 4". The entire shaded area to the right of 4 could be a possible answer.
Hope this helps.
