Answer: 
Step-by-step explanation:
The slope of a line equals to the difference between points' y-coordinates divided by the difference between their x-coordinates.
That is, if 
and 
are the point of a line,
Then the slope of the line is,
By the given diagram,
, 
, 
and 
Thus, the slope of the given line
=
⇒ Fourth option is correct.
First deal withe the numerator 4 x^2
square root of 4 is 2 and square root of x^2 = x
so square root of 4x^2 is 2x
as for the 3y we can write it as √(3y)
so answer is 2x / √(3y)
Answer:
s = 19.0
Step-by-step explanation:
To find s, use the Pythagorean Theorem.
a² + b² = c²
9² + b² = 21²
81 + b² = 441
b² = 360
b = √360
b = 18.97366596 ⇒ 19.0 (rounded to the nearest tenth)
So, s = 19.0.
Hope that helps.
The next term could be 615
because 123 x 5 = 615
