F(x) = -7x - 5 + 2x when x = -2 what is the answer please

  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

2.8 with a bar over 8 means that it is 2.8 repeated. since we want to find which rational number is equal to 2.8 repeat, let’s calculate them.a) 22/9=2.4 repeatb) 24/9=2.6 repeatc) 26/9=2.8 repeatd) 28/9=3.1 repeatsince 2.8 repeat is the answer we’re looking for, the answer is c.
