I don’t know the rest, but I think the 1st and 3rd ones are true! I hope this helps some, I’m sorry if it’s incorrect!
Pi rounded to a whole number would equal three. Circumference equals 2pi*r. The radius in this case is half of the diameter, so 4.5 cm. 2 times pi, or three equals 6 times 4.5 is 27
Answer= (3 x b)+6
Because you multiply to find the total of the golf balls. Then you'll have to add 6.
Hopefully this helped!
We have been given Marley was asked to solve 
using the Quadratic Formula. She found the discriminant first and decided she did not need to continue with the Quadratic Formula.
We are asked to determine whether Marley is correct or not.
We know when an equation is in form 
, we can use discriminant to check for the real solutions of equation.
If 
, then the equation will have two real solutions.
If 
, then the equation will have one real solution.
If 
, then the equation will have no real solutions.
Let us find discriminant.
Since 
, therefore, the equation will have no real solutions, so Marley is correct.
6000000 just add 6 zeros at the end
