Simplify the equation 8 + 3n = 20​

Prove (a) cosh2(x) − sinh2(x) = 1 and (b) 1 − tanh 2(x) = sech 2(x). solution (a) cosh2(x) − sinh2(x) = ex + e−x 2 2 − 2 = e2x + 2 + e−2x 4 − = 4 = . (b) we start with the identity proved in part (a): cosh2(x) − sinh2(x) = 1. if we divide both sides by cosh2(x), we get 1 − sinh2(x) cosh2(x) = 1 or 1 − tanh 2(x) = .

The paint recipe also calls for 1/4 cup of food coloring. tyler says mrs. mcglashan will also need 6 cups of food coloring. do u agree or disagree? explain.

Ihonestly have no clue if it's each or none.
