Answer:
D
Step-by-step explanation:
group them first :
( x3+5x2) and ( -6x-30)
then simply by gcf ( greatest common factor) :
x2(x+5) and -6(x+5)
and just add them together:
x2(x+5)-6(x+5)
bonus :
it can be written as (x2-6)(x+5)
X+(x+2)+(x+4)= 66
3x+6=66
3x=60
x=20
20,22, and 24. so 20 is the answer
