C = (6,-5) and D = (-1,-4)

CD= [ ? ]

Round to the nearest tenth.

HINT: Use the distance formula

Answer 1

• 
  `\Large\boxed{\sf{5√(2)}}`

Explanation:

Given:

• Use the distance formula.

`\Longrightarrow: \sf{\quad √(\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2)}`

• C: (6,5)
• D: (-1,-4)

`\Longrightarrow: \sf{√(\left(-1-6\right)^2+\left(-4-\left(-5\right)\right)^2)}`

Solutions:

Solve.

`\Longrightarrow: \boxed{\sf{5√(2)}}`

• Therefore, the correct answer is 5√2.
