Find the distance between<br> (-12,1) and (12,-1)
djverab [1.8K]

ANSWER: Exact Form: 2\sqrt{145}

Decimal Form:  24.08318915

STEP-BY-STEP EXPLANATION:

(-12,1)  (12,-1)

Use the distance formula to determine the distance between the two points.

Distance = \sqrt{(X2-X1)^{2  }+ (Y2-Y1)^{2} }

Substitute the actual values of the points into the distance formula.

\sqrt{(12-(-12))^{2  }+ ((-1)-1)^{2} }

Multiply  -1 BY -12

\sqrt{(12+12)^{2  }+ ((-1)-1)^{2} }

Add 12 and 12

\sqrt{24^{2} +((-1)-1)^{2} }

Raise 24 to the power of 2

\sqrt{576 +((-1)-1)^{2} }

\sqrt{576+4}

\sqrt{580}

Rewrite 580 as 2^{2}·145

Factor 4 out of 580

\sqrt{4(145)}

Rewrite 4 as 2^{2}

\sqrt{2^{2}(145) }

Pull terms out from under the radical.

2\sqrt{145}

The result can be shown in multiple forms.

Exact Form: 2\sqrt{145}

Decimal Form:  24.08318915
