How you know whether to add or subtract when use the distributive property to multiply

On a coordinate grid, point p is at (4, 3) and point r is at (−2, −5). points q and s are a reflection of both points across the x-axis. what are the coordinates of q and s? q(−4, 3), s(2, −5) q(4, −3), s(−2, 5) q(−4, −3), s(2, 5) q(−4, 3), s(−2, 5) ; -; i can't figure it out, if someone can me with the answer,that would be nice

Simplify the expression and find the missing terms. the simplest form of has in the numerator and in the denominator.

State if the two triangles are congruent. if they are, state how you know?
