Answer:
A = 78.5
C = 31.4
Step-by-step explanation:
Circumference = 2πr
r = 5
C = 2(3.14)(5)
Circumference = 31.4
Area = 
r = 5
A = 
6a-3b^2-a+b-4+7a^2
goup like terms
7a^2-3b^2+6a-a+b-4
7a^2-3b^+5a-4
The rate of change of the relationship is 6/5
<h3>Rate of change of a line</h3>
The rate of change of a line is also known as the slope of the line. The formula for calculating the slope of a line is expressed as:
Slope =y2-y1/x2-x1
Given the coordinate points (-3,-2) and (2, 4). On substituting;
Slope = 4-(-2)/2-(-3)
Slope =4+2/2+3
Slope = 6/5
Hence the rate of change of the relationship is 6/5

I think the correct answer is linear
The answer is A. A, D the reason being, is because polygons have sides C, and B have no sides so we can eliminate those immediately.
