Which expression could help you find the distance

Allisa [31]

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

Correct Expression :

$\qquad \tt \rightarrow \: |10| + | - 6|$

$\qquad \tt \rightarrow \: distance = 16\:\: units\degree$

____________________________________

$\large \tt Solution \: :$

$\textsf{Using distance formula -}$

$\qquad \tt \rightarrow \: \sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2} }$

$\qquad \tt \rightarrow \: \sqrt{( - 6 - 10) {}^{2} + (4 - 4) {}^{2} }$

$\qquad \tt \rightarrow \: \sqrt{( - 16) {}^{2} + 0}$

$\qquad \tt \rightarrow \: \sqrt{256}$

$\qquad \tt \rightarrow \: 16 \: \: units$

For short it can be expressed as :

$\qquad \tt \rightarrow \: |10| + | - 6| = 10 + 6 = 16$
