We know that
When we have

Here ,
a is the leading coefficient
c is the constant term
so, we can compare it with

so, we get

so,
leading coefficient is 5
constant term is 6......................Answer
The answer would be A. 1/4 bc you add all the marbles together then divide by the amount of the color you’re looking for
f(x) - g(x) = 2x-3 -(4x+8)
= 2x-3 -4x-8
= -2x-11
