1/2
Divide each number by 30
METHOD 1
f(3) = 20
f(4) = 30
f(5) = 42
f(6) = 56
rate of change
f(4)-f(3)=10
f(5)-f(4)=12
f(6)-f(5)=14
then the average of change is 10+12+14 /3 = 12
METHOD 2 --- faster
rate of change = f(6)-f(3) / 6-3
= (36+18+2)-(9+9+2) / 3
= 36/3 = 12

Answer:
2x-6=-16 and 3x- 10=8
Step-by-step explanation:
2x=-16+6 and 3x=8+10
2x=-10 and 3x=18
2x/2=10/2 and 3x/3=18/3
x=5 and X=6
