So, the line created from the center of the circle to the edge of the circle creates the radius. If it were a straight line from one end of the circle, through the center, to the other end, that would create the diameter.
So, the answer is radius
Answer:
Step-by-step explanation:
For this case we assume that the square have sides of length x.
So then the area for this square is given by
We have a rectangle and on this case we have this information :" the rectangle has side lengths 2 less and 2 more than a square"
So then the sides of the rectangle needs to have lengths a-2 and a+2, and if we find the area for the rectangle we got:
And as we can see th area for the rectangl is 4 units less than the area for the rectangle:
Answer:

Answer:
-9x(5j) + -9x(k)
Step-by-step explanation:
distribute -9x by multiplying it with the different numbers in the parenthesis
Answer:
A, B, and C
Step-by-step explanation:
The discriminant is denoted by b^2 - 4ac, and it can give us information about the roots of the quadratic equation.
It tells us that if:
- b^2 - 4ac < 0 , then there are 0 real solutions; they're all imaginary (involving the letter i, which is the square root of -1)
- b^2 - 4ac = 0 , then there is 1 real solution; this 1 solution has a multiplicity of 2 because the roots of the quadratic are the same number
- b^2 - 4ac > 0 , then there are 2 real solutions; there are no imaginary solutions
Looking at the possible choices, we see that all of A (A, I'm assuming you meant to write "if the discriminant is zero there is one real solution"), B, and C reflect the above properties.
Thus, they're all right.
