B=6 i believe! if you use the pythagorean theorem (a^2+b^2=c^2) then you should be able to turn 8^2 and 10^2 into 64 and 100, respectively. 100-64=36 and the square root of 36 is 6. you can plug it in by calculating 8^2 + 6^2, which equals 100! hope this wasn't too confusing XD
Answer:
let no.be x
its half= x/2
its one third= x/3
its one sixth=x/6
atq.....avg of x= x/2+x/3+x/6//3=6x/6//3=x/3
now...x/3+6=x...as the no.is 6 more than its avg
x= 9
Answer:
m > 3 for 2 solutions.
m = 3 for one solution.
Step-by-step explanation:
mx^2 - 2mx + 3 = 0
For 2 solutions the discriminant b^2 - 4ac > 0 so we have
(-2m)^2 - 4*m* 3 > 0
4m^2 - 12m > 0
4(m^2 - 3m) > 0
m^2 - 3m > 0
m(m - 3) > 0
m > 3 - this is the result for 2 solutions.
For one solution the discriminant = 0
so m(m - 3) = 0
and m = 3 for 1 solution.

The third one
