Answer:
2:5
Step-by-step explanation:
The ratio of a dimension on Figure B to the corresponding dimension on Figure A is ...
4:10 = 8.6:21.5 = 10:25 = 2:5 or 1:2.5
___
In such problems, it isn't clear if the desired answer is the ratio of two integers or if it is 1 : (something). We have expressed it both ways, so you can use the answer that matches your requirement.

Answer:
A) The expression is a trinomial.
Step-by-step explanation:
If the degree is 2, the expression would be a binomial, not a trinomial. If this answer is correct, please make me Brainliest!

so, that's the equation of the circle, and that's its center, any point "ON" the circle, namely on its circumference, will have a distance to the center of 6 units, since that's the radius.

well, the distance from the center to A is 1, namely is "inside the circle".

notice, the distance to B is exactly 6, and you know what that means.

notice, C is farther than the radius 6, meaning is outside the circle, hiking about on the plane.
I have that one too please help us ;))
