Distance between points 3,3 and 5,7?
ohaa [14]

Answer:  d = 4√5  or 4.47

Step-by-step explanation:

To find the distance of two-point, we can use the distance formula:

d=\sqrt{(x_{2} -x_{1} )^2 +(y_{2} -y_{1} )^2}\\\\d=\sqrt{(5 -3 )^2+ (7 -3)^2}\\\\d=\sqrt{(2)^2+ (4)^2}\\\\d=\sqrt{4+16}\\\\d=\sqrt{20}\\\\d = \sqrt{4*5}\\\\\\d = 4\sqrt{5}\\\\\\or d ≈ 4.47
