Sophie has factored the term completely while Carlos has not factored the term completely.
Step-by-step explanation:
We need to factor the trinomial:

Factoring:

So, the factored form of
is 
So, Sophie has factored the term completely. The terms are factored when we cannot further simplify it. Since Carlos factored (x+3)(-4x+2) 2 can be taken common from the term (-4x+2) so, it is not factored completely.

Answer:
i think its 12 sorry if its wrong
Step-by-step explanation:
The answer would be 129.85
53 x 1.45 = 76.85
76.85 + 53 = 129.85 dollars
Plug in 5 and 10 to the equation.
For the first one would be d(5) = 0.8(5)^2
Multiply the equation d(5) = 4^2
Then you just multiply the exponent the would be d(5) = 10
The second one, you just do the same thing and the answer would be d(10) = 64
