Distribute -3.2 through the parentheses
Cancel equal terms on both sides of the equation
Add the decimals
<em>Thus, The expression are equivalent at b = 9.12...~</em>
<span>Which sequence is not equivalent to the others:
1. a reflection across the y axis, fallowed by a reflection across the x axis, then a 90 degree clockwise rotation about the origin
2. a 90 degree clockwise rotation about the origin and then a 180 degree clockwise rotation about the origin
3. a reflection across the x axis, fallowed by a 90 degree counterclockwise rotation about the origin,and a reflection across the x axis
4. a 90 degree counterclockwise rotation about the origin
</span>
The answer is 9, so you would shade 9 squares.
I hope this helps! :)
