Which of the following is a trinomial? (2 points)

c2 + c + 6

c2 − 16

−8c

c3 + 4c2 − 12c + 7

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
