Prove that 32n + 5 is never divisible by 8, provided that n is a natural number. Prove that cos(x)tan(x) divided by cosec(x)^2 equals cos(x)^3 divided by cot(x)^3

Prove that cos(x)tan(x) / cosec(x^2) = cos(x)^3 / cot(x)^3 Given: <A is complementary, <B and <C is Complementary to D, and <B is congruent to <C Prove: m<A=m<D

My quesiton involves having to be given with statements and reasons.

Here is what I have so far: The property to prove is R(α). α contains more propositional variables than ∧ connectives. Base Case: α is an atom. α has no ∧ connectives - only a propositional... Proving opposite sides of a parallelogram are congruent

Given: ABCD is a parallelogram Prove: Segment AB ≅ Segment CD, Segment BC ≅ Segment AD Prove that n^2 +7n +15 is greater than n+3 is true for all values of n

I tried minus the right hand side and simplify, but that did not work. I tried simply the left hand side first and even that didint work. Please help! Thanks Geometry proofs fill in the blank help!!! ASP
