Iwas super busy today, and didn't have time to finish my math homework. i really hope you guys can me, as i need the points for this. all you need to do is to simplify the expressions shown. i already have the answers, i just need to know how to show my work. if it , the answers are: 11) 50/3 - 35/12n12) -19.58x + 18.4813) 13/20 - 10/7v14) -23/20 + 13/30x and any explanations would be very , as it would me a lot in the future.

Given: abcd is a square. prove: ac ? bd. we are given that abcd is a square. if we consider triangle aeb and triangle aed, we see that side is congruent to side ad because sides of a square are congruent. we know that side ae is congruent to side ae by using the . finally, we know that side de is congruent to side because the diagonals of a square bisect each other. therefore, triangle aeb is congruent to triangle aed by congruency. we see that angle aed and angle aeb are a linear pair, and congruent by cpctc. thus, the measure of these angles will be 90°, and diagonal ac is perpendicular to diagonal bd by the .
