How many units long is a line segment whose endpoints have(-3,7) coordinates (2,-5) and ?
So i did distance fourmula and i got But than is entered √169 and it was rong
\(\sqrt{ \left( 2 - -3\right)^2 + \left(-5 - 7\right)^2}\\ \sqrt{ \left( 2 + + 0\right)^2 + \left(-5 - 7\right)^2}\\\sqrt{\left( 5\right)^2 + \left(-12\right)^2}\\\sqrt{ 25 + 144 }\\ \sqrt{ 169 } \approx 13\)
