Answer:
In this equation "a" is a variable.
Step-by-step explanation:
A variable is a term used that does not necessary have a value attached to it. Instead any value can be input in for it.
The shortest side is 9, longest is 17 of the triangle IS NOT a 90 degree triangle
50 is not a perfect square because it does not have a perfect square root where as 49 is 7, 121 is 11, and 1 is 1
Easy
the radius is the distance from the center to a point on the circle
we are given
center=(7,1)
a point=(8,7)
find the distance
distance formula
D=
so the distance between point and center is radius
D=
D=
D=
D=√37 units
radius is √37 units
