Ijust missed a couple says of school and i need someone to explain how to do this to me:

Valentina is subtracting from . she finds the lcd to be 15y2. what is valentina's next step?

The distance between two points is 6.5cm and scale of map is 1: 1000 what's the distance between the two points

Ineed asap. 35 points. in order for two polygons to be similar, two conditions must be met. first, all pairs of corresponding sides must be in proportion. second, all corresponding angles must be congruent. prove that angle congruence is not enough, by itself, to establish that two polygons are similar. do this by describing or drawing two polygons that are not similar but whose corresponding angles are all congruent.
