Answer:
<em>Perimeter of ABC = AB + BC+AC. Replace letters with equations.</em>
<em>3x^2-7x+2</em><em> = </em><u><em>2x^2-10x+6 + x^2-x-4 + AC</em></u><em> = </em><em>3x^2-11x+2 + AC</em><em>.</em>
<em>AC = 4x;</em>
The expression is Undefined for x=0, assuming you intend 1/(-8x).
x=0 is "nonpermissible"
6000 - 1800 = 4200
4200/4 = 1050
so she donated 25% to charity

Step-by-step explanation:
y(x) is even or odd according as y(−x)=±y(x) . Here, #y(-x)=-(-x)^3=-(-x^3)=x^3=-y(x). So, y is an odd function of x.
