Answer:

2xy is the greatest common factor of the three monomials.

Step-by-step explanation:

There are three monomials such that greatest common factor of first and third monomial is 2xy and greatest common factor of second and third monomial is 2x²y.

As we know greatest common factor means, common prime factors of two numbers or expressions.

Greatest common factors of 1st and second and greatest common factors of 2nd and third monomials have been given.

So, common prime factors of these two greatest common factors will be greatest common factor of all three monomials.

Prime factors of 2xy = (2)(x)(y)

Prime factors of 2x²y = (2)(x)(x)(y)

So common factors are (2)(x)(y) which is the greatest common factors of all three monomials.

The equation R=-0.0028t+20.8 can be used to predict the world record in the 200-m dash, where R is the record in seconds and t i
Finger [1]

Answer:

The world record for the 200-m dash will be set at 18.0 seconds in the year 2920.

Step-by-step explanation:

To find what year the record will be 18 seconds, substitute 18 in for R, and solve for t.

-0.0028t + 20.8 = R

-0.0028t + 20.8 = 18

-0.0028t = -2.8

t = 1000

The record for the 200-m dash will be 18 seconds after 1000 years. To find which year this record will be set in, add 1000 to the original date, 1920.

1920 + 1000 = 2920
