Can someone explain this to me since I don’t get it that well? Draw axes of symmetry of these shapes. Circle the shapes that have vertical symmetry.

Question 25

Which of the following is the correct ratio for converting kilograms to grams

(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)

Could somebody me with this radical simplification?
