[1 mark]

• A. $4\sqrt{2}\text{units}$
• B. $10\text{units}$
• C. $20\text{units}$
• D. $8\text{units}$

Answer 1

The correct option is C $20\text{units}$

The distance between the points $A(10,-8)$ and $B(-6,4)=$
$\sqrt{\left(\right(-6)-(10){)}^2+(4-(-8){)}^2}=\sqrt{{16}^2+{12}^2}=\sqrt{400}=20\text{units}$
