In a park, a sidewalk is built around the edge of a circular garden as shown below. The sidewalk is 5 feet wide, and the garden measures 20 feet across. Which measurement is closest to the circumference of the outer edge of the sidewalk?

A.
75ft

B.
90ft

C.
30ft

D.
700ft

B.  90ft

Step-by-step explanation:

-The diameter of the outer edge will be equivalent to the garden's diameter plus twice the sidewalk's width:

#The outer circumference can then be calculated as:

Hence, the measurement closest to this circumference value is 90 ft

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

the first one, all those points on the line just make a strait line.
