Prime only has two factors one and its self a composite number has more factor than one and its self
exsample: 12 - 1,2,3,4,6,12 = 12 is a composite number
7 - 1,7 =prime number
Answer:
60π
Step-by-step explanation:
2π(3 × 7 ) + 2π (3)^2
Distribute: 2x3x7 and 2x3^2
42π + 18π
That gives 60π.
The numbers they are looking for are numbers that are simple but made up. For example, start with 0. Plug 0 in for x, so the corresponding value of y is 10. For a second value, you could do 2. When x=2, y=11, etc. So essentially, put in some simple numbers for x, and solve for y. :)
