Find the distance between (-3,-2) and (1,4), simplify form
:
You should know the distance formula which is: d = sqrt%28%28x2-x1%29%5E2+%2B+%28y2-y1%29%5E2%29
:
In your problem x1 = -3, y1 = -2; x2 = 1, y2 = 4, so you have:
d = sqrt%28%281-%28-3%29%29%5E2+%2B+%284-%28-2%29%29%5E2%29
:
d = sqrt%28%281%2B3%29%5E2+%2B+%284%2B2%29%5E2%29; remember, minus a minus, is a plus
:
d = sqrt%284%5E2+%2B+6%5E2%29;
:
d = sqrt%2816+%2B+36%29;
:
d = sqrt%2852%29= sqrt%284%2A13%29 = 2%2Asqrt%2813%29; extracted 2^2
