A bathtub is being filled up with water at a constant rate described by the equation w = 3.5t. The w represents the amount of water in gallons, the t represents the time in minutes. What does the 3.5 tell us in this situation?

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
