Suppose two fractions be

  • a/b
  • c/d

Now

\\ \rm\Rightarrow \dfrac{a}{b}+\dfrac{c}{d}

  • Find LCM of b and d
  • divide LCM by b and d and multiply with a and c respectively

\\ \rm\Rightarrow \dfrac{ad+bc}{bd}

4. Find the distance between the two points. Round to the nearest tenth if necessary.
Archy [21]

Answer:

Distance = 7.8 units

Step-by-step explanation:

In coordinate geometry, the distance between the 2 points is given by

Distance = \sqrt{(x1-x2)^{2} + (y1-y2)^{2} }

where (x1,y1) and (x2,y2) are coordinates of the 2 points.

Above the 2 points given are, (-2,-1) and (3,5).

<em>x1 = -2 , y1 = -1 , x2 = 3, y2 = 5</em>

<em>Distance = \sqrt{((-2)-(3))^{2} + ((-1)-(5))^{2} }</em>

<em>Distance = \sqrt{61}</em>

<em>Distance = 7.8102 units</em>

To the nearest tenth, Distance = 7.8 units
