2a because 4a and 10a if you do the math... the factors of 4 are 1,2,4 and the factors of 10 are 1,2,5,10
2 is the only one greatest factor that they both have.
Answer:
21.1 inches
Step-by-step explanation:
The gecko is 3.5 inches to start with.
If it grows at a rate of 1.2 inches per month for the first 12 months, after 12 months the gecko will be 14.4 inches larger. (Because 12 times 1.2 is 14.4)
So, after 12 months the gecko will be 17.9 inches.
Since the gecko grows at 0.4 inches per month for the next 16 months, and the gecko has grown for 20 months, all we need to do is subtract 12 from 20 (since we already calculated how long it will be after 12 months) and multiply that by 0.4.
Since 20 - 12 is 8, we just multiply 8 by 0.4 to get 3.2. We now add 3.2 to 17.9 to get 21.1 inches.
Hope this helps!

So it's just 622 x 3.14 (which is obviously rounded)

Answer:
40in
Step-by-step:
to get from 12 to 30 you multiply by 2.5
this is the scale factor
then you do 16 x 2.5 which is 40
pq (p to q) is 40in
when you dive the fractions
2/3 = 0.666666
6/10=0.6000
4/5 = 0.80
6/5 = 1.2
so the answer would be 2/3
