1 answer:

7 0

$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} = \sqrt{(-22 - 7)^2 + (12 + 17)^2}\\= \sqrt{(-29)^2 + 29^2} = \sqrt{841 + 841} = \sqrt{1682} = 29\sqrt{2}$

Consecutive numbers differ by one. So, if $x$ is the first, the three numbers are

$x,\ x+1,\ x+2$

The sum of the first and third integer is

$x+(x+2)=2x+2$

(f - g) (144) Multiply 144 by both variables in the other set of parentheses.

[(144) (f) - (144) ( g)] Simplify

144 f - 144g
