I say its 11. Since the distance between the two points is 11.
<h3>The distance between the pair of points is 2.8 units</h3>
<em><u>Solution:</u></em>
Given that,
Points are W(2, 5), U(4, 3)
<em><u>Distance between two points is given as:</u></em>

From given,

<em><u>Substituting the values we get,</u></em>


Thus the distance between the pair of points is 2.8 units
<span>x = 25
(x – 7)2 = 36
(x*2) - (7*2) = 36 : multiply x*2 and 7*2 because of distributive property
2x - 14 = 36 : multiply
2x = 36 + 14 : add 14 to combine like terms
2x = 50 : add
x = 50/2 : divide 50 by 2 to get x alone
x = 25 : simplify </span>
