C is a circle with radius r. Which of the following is true? Select all that apply

A. The diameter of C is 2r

B. the circumference of C is pi*r

C: the circumference of C is 2pi*r

D. One quarter of the circle has length (pi*r)/4

E. One quarter of the circle has length(pi*r)/2

A and C and E are correct

Step-by-step explanation:

Circumference is 2 * pi* r

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
