B 56ft
C 28ft
D 11ft

Can someone me with this problem . show your work .

∆red ≅ ∆ by rule will give brainiest if possible

(round one decimal place and answer in interval notation) c. when is the displacement negative? (round one decimal place and answer in interval notation) d. when is the particle’s acceleration positive? (round one decimal place and answer in interval notation) e. when is the particle’s acceleration negative? (round one decimal place and answer in interval notation)
