The table shows how much a store charges for certain numbers of pencils... Which equation could be used to calculate the cost, c, of any number of pencils, p? A. C = 0.12p B. C = 0.12+p
C. C = 0.48 + 0.12p D. C = 0.48p

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
