Answer:
8i+51
Step-by-step explanation:
I'm pretty sure it is just 8i+51 because there isn't really anything you can do with the variable.
Part A: the radicand is the same as the discriminant, therefore is b2 - 4ac
In 9x^2 - 16x + 60 = 0, a = 9, b = -16, c = 60
so b2 - 4ac =

Part B: Solve 4x^2 + 8x - 5 = 0
What would make 8? (5×2)-2 = 8, so:
(2x+5)(2x-1) = 0
2x+5 = 0
2x = -5
x = -5/2
2x-1 = 0
2x = 1
x = +1/2
So the solutions are: -5/2, +1/2
Answer:
Units of Capacity (Volume)
The basic unit of volume or capacity is the litre. The most commonly used units in cooking are the litre and the millilitre.
My best guess is D.
But I'm not too sure about it.
1/10 of 3,000
(1/10)(3000/1)
=(1)(3000)/(10)(1)
=3000/10
=300
