Answer:
C
Step-by-step explanation:
Given
x³ + 3x² + 3x + 9 ( factor first/second and third/fourth terms )
= x²(x + 3) + 3(x + 3) ← factor out (x + 3) from each term
= (x² + 3)(x + 3) → C
Answer:
Correct

Answer:
it equals 57,471
Step-by-step explanation:
5000000÷87=57,471
To find the area its A=1/2Bh
Radius of sphere = 18/2 = 9 cm
Volume of sphere = 4/3 πr^3 = 4/3 x π x (9)^3 = 972 π cubic cm
If the diameter is reduced by half, then
Volume = 4/3 x π x (9/2)^3 = 4/3 x π x (9)^3 x (1/2)^3 = 1/8(972)
Therefore, new volume is 1/8 of original volume.
