Verify this identity

cos(-x)+tan(-x)/cot(x)=sec^2(x)

$7.50x+$4.50y=midk it's been awhile since i've done one of these

685,000,000 ( hope this )

55+330+44=884is the answe

  example you can find the perimeter by addig all of its respective sides as such: (12+x)+(12+x)+(7+y)+(7+y).  adding like terms will result in   2x+2y+38    if you chose  xy+7x+12y+84, you multiplied the two sides to find the area.  if you chose  x+y+19
