Answer:
see below
Step-by-step explanation: 6 23 17 30
the length CD is the square root of the delta X value squared + the delta Y value squared
a² + b² = c² is the common form for this problem use
ΔX² + ΔY² = CD²
ΔX = X2 - X1 ΔY = Y2 - Y1
ΔX = 2 - (-2) ΔY = 5 - (-5)
ΔX = 4 ΔY = 10
4² + 10² = CD²
16 + 100 = CD²
116 = CD²
√116 = √CD² = CD
√(4 × 29) = CD
2√29 = CD the first option
