Two students, carlos and sophie, factored the trinomial -4x2 − 10x + 6. sophie factored it as -2(2x − 1)(x + 3) and carlos factored it as (x + 3)( -4x + 2). indicate which student factored the trinomial completely and which student did not, and explain why. (15 points)

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
