The answer to you question is b
The answer is 1000 because 62x4= 248 and then you take 248 and multiply it by 4 and you get 992 then you have to multiply 4x2 which is 8 and then when you add 992+8, you would get 100 ;)
The correct answer is: [A]: " 4x³ + x² + x + 3 " .

Explanation:
______________________________________________________
(3x³ + 2x² + 2x + 1) + (x³ − x² −<span> x + 2) =
</span>↔ (x³ − x² − x + 2) + (3x³ + 2x² + 2x + 1) =
<span>
</span>(x³ − x² − x + 2) + (3x³ + 2x² + 2x + 1) =
x³ − x² − x + 2 + 3x³ + 2x² + 2x + 1 ;
<span>
Combine the "like terms" ;
x</span>³ + 3x³ = + 4x³ ;
−x² + 2x² = + x² ;
− x + 2x = + x ;
+ 2 + 1 = + 3 ;

And rewrite:
_____________________________________________________
→ " 4x³ + x² + x + 3 " ;
→ which is: "Answer choice: [A]: " 4x³ + x² + x + 3 " .
