Distance formula: $\sqrt{(x_{2}-x_{1} )^{2}+(y_{2} -y_{1})^2 }$

Plug in the points:

$\sqrt{(2-(-7))^{2}+(3-3)^2 } = \sqrt{(9)^{2}+(0)^2 } = \sqrt{(9)^2} = 9$

-x - 1 = 221 + 2x <br> plzzzzzzzzz help

Otrada [13]

$Simplifying
-1x + -1 = 221 + 2x

Reorder the terms:
-1 + -1x = 221 + 2x

Solving
-1 + -1x = 221 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.
-1 + -1x + -2x = 221 + 2x + -2x

Combine like terms: -1x + -2x = -3x
-1 + -3x = 221 + 2x + -2x$
$Combine like terms: 2x + -2x = 0
-1 + -3x = 221 + 0
-1 + -3x = 221

Add '1' to each side of the equation.
-1 + 1 + -3x = 221 + 1

Combine like terms: -1 + 1 = 0
0 + -3x = 221 + 1
-3x = 221 + 1

Combine like terms: 221 + 1 = 222
-3x = 222

Divide each side by '-3'.
x = -74

Simplifying
x = -74$
