There are 6 red marbles, 10 blue marbles, and 9 green marbles in a bag. what is the probability that you will randomly draw either a red or a blue marble?

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

What is the gcf of 20c^3-5c^4+30c^6

Does the construction demonstrate how to copy an angle correctly using technology a) yes the distance between points a and f was used to create circle h b) yes the distance between points f and g was used to create circle h c) no the distance between points a and f was used to create circle h d) no the distance between points f and g was used to create circle h
