Step-by-step explanation:

we know that

The definition of π is the circumference C of any circle divided by its diameter D

so

First, find the length of the Diameter and the length of the circumference of the circle.

Next, divide the length of the circumference by the length of the diameter and set up an equation where the ratio  equals Pie

Then, solve the equation for the circumference

solve for C

That means---> isolate the variable C

Finally, substitute 2 times the radius for the Diameter

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
