If the radius of the sphere is doubled, the volume would quadruple. Think of the sphere as a cube instead and if you were to double the sides, the area would be 4xs bigger. Hope this helps! :)
To have 2 real number solutions the discriminant b^2 - 4ac must be greater than zero.
so the condition for 2 real roots in this equation is:-
b^2 - 4*1*5 > 0
b^2 > 20
b > sqrt 20 ( positive root) Answer
Answer:
a
Step-by-step explanation:
You can use expanded form: 4 X 700, 4 X 50, 4 X 4, = 3016.
You can use the Distributive Property of Multiplication: (4 X 500) + (4 X 254) = 3016.
