Answer:
A and B
Step-by-step explanation:
1/4x^2 = (1/2x)^2
If you were to factor you would do what my teacher likes to call reverse foil so it would look like this (x-9)(x+4) so what you do is you brainsrorm to see what multiplies what to get that and 9*4=36 so that is how you factor -36 to find the -9
Hope this helps if I'm correct if not I will try to find the answer
To find the percent of increase get the difference between the prices and then divided by the oringinal price and then time that by 100
increase =
Y=mx+c
-4=6(12)+c
-4=72+c
-4-72=c
c=-76
y=mx+c
y=6x-76
