Each time a touchdown is scored at a football game 6 points are added to the score of the scoring team. a team already has 12 points what rule represents the number of points as an arithmetic sequence when n is the number of touchdowns scored a. a(n)=12+6n b. a(n)12-(n-1)6 c. a(n)=12+(n-1) d. a(n)=12+(n-6)

You can find the constant of proportionality by finding the ratio of

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
