Question

Can anyone do this quick please ​

Answer 1

-3 because -8 plus -2 equal 10 and 6 plus - 1 equal 7 they need -3 to get to 10

Answer 2

I just did this one because it said distance formula of points. I don't know what the second line is saying.

Explanation:

A (-8,-2) = (x1, y1)

B (6,-1) = (x2,y2)

now,

distance formula,

=

`\sqrt( x2+ x1)^(2) + (y2 - y1) ^(2)`

=

`\sqrt( 6 + 8)^(2) + ( - 1 + 2)^(2)`

=

`\sqrt(14)^(2) - (1)^(2)`

=

`\sqrt(196 - 1)`

=

`√(195)`
