Answer:
7.5
Step-by-step explanation:
mean= sum all/number of all
(2+8+6+8+6+8+10+12)/8=
60/8=7.5
3x^2-5x-24=0
3x^2-5x=24
x^2-5x/3=8
x^2-5x/3+25/36=8+25/36
(x-5/6)^2=313/36
x-5/6=±√(313/36)
x=5/6±√(313/36)
x=(5±√313)/6
p=(5+√313)/6
q=(5-√313)/6
Answer:
-7/12
Step-by-step explanation:
I used my calculator
It would equal 8 because 2 times 2 equals 4, than 4 times 2 equals 8. Hope this helps!
