Answer 1/4
Step-by-step explanation:
3/12 divided by 3 is 1/4
<span>The expression of the square root of 19x must be simplified when x is equal to 28. This is because possible factors of 28 can be seen to be 4 and 7, and 4 is a perfect square. This means it can be pulled outside of the square root when evaluated. The other options include only prime factors that could not be pulled out. (3,5), (3,7), (1,41)
28 simplifies as such:
Sqrt(19*28) = Sqrt(19*4*7) = 2*Sqrt(19*7) = 2*Sqrt(133).</span>
Answer:
Step-by-step explanation:
Let the equation of line is 
, where 
is the slope of the line.
It passes through 
.
(<em>Slope of the line</em> joining 
)
Hence slope of the given line
Equation of line is: 
The line passes through 
Check if 
is on the line
Hence line passes through 
.
Check if 
is on the line
