The answer is 8 because you use the order of operations. So it would be 16 divided by 4, then you would do 4+4 which is 8
We can only see one graph here

Break the expression into group:

factor out x from 4x² - 5x : x (4x-5)
factor out 3 from 12x-15 : 3 (4x-5)

factor out common term (4x-5) :

hope this helps!
There are 6 possible outcomes on a dice. Meaning when you roll it it could be any of them. Because 3 is one of the 6 the answer would be 1/6
The geometric sequence is 3, 9, 27, 81, 243, 729 because each time it is multiplied by 3.
