Question

AB is a straight line of 9 units. If A has co-ordinates (-3,- 14) and B has
co-ordinates (x,-5), use the distance formula to find the value of x.​

Answer 1

Answer:

$\sqrt{ {(x + 3)}^{2} + {( - 5 + 14)}^{2} } = 9 \\ \\ \sqrt{ {(x + 3)}^{2} + 81 } = 9 \\ \\ {(x + 3)}^{2} + 81 = 81 \\ \\ {(x + 3)}^{2} = 0 \\ \\ x = - 3$
