Hello, everyone! i am in high school and i need with my geometry homework! i will also mark you as the brainliest answer if you answer it clearly!

Add or subtract polynomial : –12qr? +13rq?

Identify the converse of the following conditional: if a point is in the first quadrant, then its coordinates are positive. if the coordinates of a point are not positive, then the point is not in the first quadrant. if the coordinates of a point are positive, then the point is in the first quadrant. if a point is in the first quadrant, then its coordinates are positive. if a point is not in the first quadrant, then the coordinates of the point are not positive.

What is the solution to the equation? k/6.4=8.7 2.3 5.568 15.1 55.68
