The correct answer is the last set of numbers
Answer:
2√3
Step-by-step explanation:
So √12 is in radical form. I think what you are asking for is to reduce the expression to its **simplest** readical form.
So 12 = 4*3, √12 = √4 * √3.
So 12 = 4*3, √12 = √4 * √3.
We can ‘reduce’ this by noting that √4 =2, so the expression becomes 2√3.
This cannot be further reduced because 3 isn’t a square or divisible by a square, so 2√3 is the simplest radical form.

Answer:
r = 1
Step-by-step explanation:
Direct variation describes a relation ship in which two variables are directly proportion and is represented as,
y = rx or
![\sf r =\dfrac{y}{x}](https://tex.z-dn.net/?f=%5Csf%20r%20%3D%5Cdfrac%7By%7D%7Bx%7D)
From the table,
![\sf r =\dfrac{5.8}{5.8}\\\\r = 1](https://tex.z-dn.net/?f=%5Csf%20r%20%3D%5Cdfrac%7B5.8%7D%7B5.8%7D%5C%5C%5C%5Cr%20%3D%201)
