8+2m^3 is the answer. Hope it help!
Test for symmetry about the x-axis: Replace y with (-y). Simplfy the equation. If the resulting equation is equivalent to the original equation then the graph is symmetrical about the x-axis. Example: Use the test for symmetry about the x-axis to determine if the graph of y - 5x2 = 4 is symmetric about the x-axis.
Test for symmetry about the y-axis: Replace x with (-x). Simplfy the equation. If the resulting equation is equivalent to the original equation then the graph is symmetrical about the y-axis.

I didn't fully understand the question but this is the best I can do! Hope this helps! :D
Do you have a better picture?
<span>$60.00 - $42.00 = </span><span>$18
</span><span>$18 / $60 = 0.30 = 30%
Answer
Decrease 30%</span>
X would equal 81 because the square root of 81 is 9.
9 x 9 = 81
