Well it depends.What does the variable b represent?
Need more detail to solve
The radius is √25=5 in this case.
find the area of each triangles first. (the pentagon can be divided into 5 isosceles triangles)
the two equal sides are 5 each, the angle between them is 360/5=72 degree, so the base side is 2*5*sin36, and the height is 5*Cos36
the area of each triangle is (1/2)*2*5*Sin36*5*Cos36
the total area of the 5 triangles is: 5*(1/2)*2*5*Sin36*5*Cos36
use a calculator: A≈59.44
I think its D because don’t functions only have 1 equation?
Linear equations are equations that have constant slopes
The linear equation that represents the table is (a) y = 7x +4
<h3>How to determine the linear equation</h3>
Start by calculating the slope (m) using:

So, we have:

Simplify


The equation is then calculated as:

So, we have:

Open the brackets


Hence, the linear equation that represents the table is (a) y = 7x +4
