15.75 meters... that's the area
Expanded form of 76 is 70+6
expanded form of 18 is 10+8
There are 3 numbers: 4.25,4.50,and 4.75.
The given lines are perpendicular
Step-by-step explanation:
if Two lines are perpendicular then their slopes are
m
Where m₁ is slope of first line and m₂ is the slope of second line.
Since the lines are in slope-point form the standard form is:

where m is the slope
The slope of first line y= -9/5x + 1/5 is: m₁ = -9/5
The slope of second line y= 5/9x + 2/9 is: m₂= 5/9
So, m
i.e 
So, The given lines are perpendicular
