Find the inverse of: If x equals 4, then 3x + 8 equals 20. Hint: Given an implication p q, the related implications are: -> Its converse Its inverse Its contrapositive not q not p deb not p not q -> A. If 3x + 8 equals 20, then x equals 4. B. If x doesn't equal 4, then 3x + 8 doesn't equal 20. C. If 3x + 8 doesn't equal 20, then x doesn't equal 4.
