nCp = n! / (p!)*(n-p)!
so 12C8 = 12! / (8!)*(4!)
= 11880 / 24
= 495
ans is C

Answer:
(2x+3) y (3x+5)
Step-by-step explanation:
For this exercise we have that the volume is
V = 6x ^ 3 + 31X ^ 2 + 53x + 30
H = X + 2
The formula for the Volume its
V = H * L * W
for find L and W (width and length) we divide V / H = L * W
So,
this division is in the attachment
so, L * W = (2x + 3) * (3x + 5)
The answer is False as they add up to 20 only
hope it helped ;)
