Hi there!
To factor this expression, you must first find the greatest common factor of each term, 16x and 40y.
To do this, first list the factors of each coefficient since they do not share any variables:
16:1,2,4,8,16
40:1,2,4,5,8,10,20,40
Notice that among the factors of each term, 8 is the greatest common factor.
Finally, factor 8 from the expression to get 8(2x+5y) as your final answer.
Hope this helps, and have a nice day!
Can you take a picture of the problem?
Answer: A pull a vowel
Step-by-step explanation: its unlikely he will pull a consonant since a consonate is when your lips touch together (like "p" "m" "b") pulling an E or P is low, but a vowel covers A,E,I,O, and U so it covers four letters, so your best bet is A.
2a because with 18a and 20ab they both have "a" in common and they are even thus multiples of 2 leaving you with 2a(9,10b)
