Explain how you could use the greatest common factor of 8 and 20 and the distributive property to write 8 + 20 as a product

Step-by-step explanation:

To write 8 + 20 as a product, factor out a common factor.

To find the greatest common factor, write the prime factorizations.

8 = 2³

20 = 2² × 5

GCF = 2²

The greatest common factor is 4.  So if we factor out a 4 from the sum:

8 + 20

= 4 (2 + 5)

= 4 × 7

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
