Find the distance between (-4,-3) and (-8,2)
Masja [62]

The distance (r) between any two points (a,b) and (c,d) is :—

r =  \sqrt{{(a - c)}^{2} +  {(b - d)}^{2}  }

Putting the values,

\sqrt{ {( - 4 + 8)}^{2} +  {( - 3 - 2) }^{2} }

r =  \sqrt{16 + 25}

r =  \sqrt{41}

The distance between the points is √41

x = 3/4 * 4/5
x = 12/20 which reduces to 3/5

check..
1 1/4 * 3/5 =
5/4 * 3/5 =
15/20 reduces to 3/4 

so u would multiply 1 1/4 by 3/5 to get 3/4
