A garden shop always sells the same. under if plants per box. Using the information in the table, how many plants will be in 8 boxes

Can someone me out here and the tell me the greatest common factor

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28

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) = .
