Answer:
<h2>
B. (x-4)(x+i)(x-i) </h2>
Step-by-step explanation:
x³-4x²+x-4=
=x²(x-4)+(x-4)
=(x-4)(x²+1)
=(x+4)(x-i²)
<h3>=
(x-4)(x+i)(x-i) </h3>
Yes he is correct because if you do the algorithm, 0+3=3 and 20+40=60 and 60+3=63. There is no regrouping needed.

Step-by-step explanation:
Volume= [(20+20) x (20+20) x 100] - (20 x 20 x 100)
=120000cm^3
surface area= 2 x 40 x 100 + 2 x (40 x 40 - 20 x 20) + 4 x 20 x 100
=18400cm^2
