A. Radii of congruent circles are equal.

Step-by-step explanation:

We have been given an incomplete sentence. We are supposed to fill in the blank from our given choices.

Sentence:

Radii of circles are equal.

We know that radius of a circle is distance from the center circle to any point on the circle.

The radii of two circles will be equal, if and only if, both circles are congruent, therefore, the correct choice is opton A.

good luck!

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
