Question

what is the distance between points R (- 7 , - 4) and T (3, -8)

a) 4 root 29
b) 16 root 3​

Answer 1

Answer:

2√29 is the correct answer.

Explanation :

D = √(X2 - X1)² + (Y2 - Y1)²

D = √{3 - (-7)}² + {-8 - (-4)}²

D = √(3+7)² + (-8+4)²

D = √(10)² + (-4)²

D = √100 + 16

D = √116

D = √2×2×29

D = 2√29
