Answer:</h2>
D. Distance formula
<h2>
Step-by-step explanation:</h2>

As in the statement:
<em>The distance form</em>
to
is
<em>whose justification is the </em><em>Distance Formula. </em>
<em />
Here in this statement the justification is also the Distance Fromula, so we take the distance from
whose result is also 2 and is the radius of the circle.
Answer:

Step-by-step explanation:
(-2,1)=(x1,y1)
(4,5)=(x2,y2)
d=?
d=
Answer:
the answer of given question is $400.
You mean (x-8)/3 = 3 ...right?
You would multiply both sides by 3.
Then, add 8 to both sides.
x=17
Average speed = (distance final - distance initial)/(time final - time initial)
Average speed = (30-0)km /(100 -0)min = 3/10 km/min
3/10 km/min *60 min/1 h = 180/10 km/h= 18 km/h
