The difference would be subtracting the variables and the dividing the difference by 2
I got 3x^2 + 12x + 4. I recommend you verify my answer, so you have to combine like terms in the first expression then add all the expressions.
17 by 2 because 34 divided by 2 is 17
The real answer is y=-1/2+9 !
So change from 50 to 35
first find change
50-35=15
50=100%
15=x%
percent means parts out of 100
15 out of 50=x/100
15/50=x/100
30/100=x/100
30=x
the answer is 30% change
