Find the circumference and the area of a circle with diameter 2 ft

Step-by-step explanation:

C=2πr

A=πr2

r is radius

diameter is twice the amount of the radius or radius is half of diameter

in this case the radius would be

C=2 x 3.14 x 1

=6.28

A= 3.14 x 1^2

=3.14

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

2x^2+5x+17
