There are 440 thousands :)
Answer:
So if Jill, Sabrina and Kelly write the report together, it will take 4 hours.
Step-by-step explanation:
We know that Jill and Sabrina can write a lab report together in 6 hours. We know that all people work at the same rate.
So, we conclude that it will take Jill or Sabrina 12 hours if they write the report themselves. Kelly will also need 12 hours to write a report because we know everyone is working at the same speed.
We conclude that if all three work together they will need three times less time. We get:

So if Jill, Sabrina and Kelly write the report together, it will take 4 hours.
Answer:
132
Step-by-step explanation:
area of square =4l
= 4× 11
=44
total length =44×3
=132m
(1)the GCF for the polynomial 
4x^3 = 2*2* x* x* x
2x^2y = 2*x*x*y
Greatest common factor is 
(2) the GCF for the polynomial 


GCF is 
(3) the GCF for the polynomial


GCF is 
(4) the GCF for the polynomial 


GCF is 
I think it’s the second option
