Answer:
f(86)-f(82)
Step-by-step explanation:
well f of 82 = 2 plus _ plus _ plus _ and f of 86 is 2+_+_+_ subtract them
  (A)  3            (B)   4           (C)   47            (D)   59             (E)   83
these are some possible answers so the answer is b, 4

Answer:
a=2
b=0
c=12 
Step-by-step explanation:
The standard form of a quadratic equation is ax²+bx+c=0 
Here's the given equation: 
2x²+12=0 
You might notice that the term bx is not there (there is just ax² and c). That means that b is 0. 
The term 2x² is the term ax² in this equation. The coefficient in the term is 2, so that means that a is 2 
12 has no variable, so that means it'll be c in the equation. 
Hope this helps!
