Answer:

x = 3

Step-by-step explanation:

All the angles of a square are 90°

The diagonals bisect the angles , then

5x² = 45 ( divide both sides by 5 )

x² = 9 ( take the square root of both sides )

x = \sqrt{9} = 3

How are using graphs equations and tables similar when distinguishing between proportional and nonproportional linear relationsh
MrMuchimi
When using graphs to find proportional and nonproportional is easy. When it's proportional it goes right through the origin and it's nonproportional it doesn't go through the origin.
