Question

Find the length of the side (-2,7) and (-4,5)

Answer 1

..
`√([(-4-(-2)^2) + √((5-7)^2) =\\\\√((-2)^2+ (-2)^2) = √(4+4) =√(8) = 2√(2)`

length of the side (-2,7) and (-4,5) : 2√2

Explanation:

Answer 2

2 square root 2 = 2.83 units

Explanation:

Square root [(-4 - - 2)^2 + (5 - 7)^2]
= square root (-2^2 + -2^2)

= square root (4+4) = square root 8 (8= 2*2*2)

= 2 square root 2
