Area of a triangle equals 1/2 Bh
base = 2.5 height = 5
2.5 x 5 = 12.5/2 = 6.25
since there are 4 sides you multiply by 4
6.25 x 4 = 25
Now to do the bottom you multiply 2.5 x 2.5 = 6.25
6.25 + 25 = 31.25<----ANSWER
Hope this helps
You'll actually need to graph for the first segment
but the second part can be solved with algebra
The equation of the line is y(x)=-x
if we test the co0ordinates we can find if the point lies on the line
(5,5)
y(x)=-x
Using the x co-ordinate
y(5)= -5
y=-5
Leaving us with (5,-5)
Because (5,-5) is not (5,5)
This is not a point on the line
The slope of the line is -1
Answer:
9 sides
Step-by-step explanation:
exterior angle + interior angle = 180° , so
exterior angle + 140° = 180° ( subtract 140° from both sides )
exterior angle = 40°
The sum of the exterior angles of a polygon = 360°
Dividing sum by the measure of 1 exterior angles gives number of sides
number of sides = 
= 9
