C because first you would find the circumference of the circle which is pi times diameter, which is 18.84 but since it is a semi-circle you would divide by 2 which is 9.42. Then you do 3+3=6 + the length which is 6 so you get 12. 12+9.42=21.42 and if you round that to the nearest tenth it is 21.42.
The problem above can be modelled as shown in the graph below
At

Answer:
The binomial 14
- 35x can be factored as 7x(2x+5)
Step-by-step explanation:
When factoring, you want to factor each constant or variable by their greatest common factor (or GCF). Since
and
has a greatest common factor of 7x, factor each term by 7x and you'll get
.
