Question

Which expression gives

point S and point T?
A. √10² + 11²
B. √√6² +3²
C. √√4²+7²
D. √2² +82
E. 2² +1²

Answer 1

B

Explanation:

to find the distance d use the distance formula

d =
`\sqrt{(x_(2)-x_(1))^2+(y_(2)-y_(1))^2 }`

with (x₁, y₁ ) = S (2, 4 ) and (x₂, y₂ ) = T (8, 7 )

d =
`√((8-2)^2+(7-4)^2)`

=
`√(6^2+3^2)`
