14a+8s=376
7a+11s=272
she found that the price of one student ticket is $20 and the price of one adult ticket is $12. which statement explains krissa’s error?

b the solution works in both equations.
c the solution only gives the correct price for one student ticket.

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) = .
