An antique Persian carpet has an area of (x^2 + x - 20) ft^2 and a length of (x + 5) feet. The rug is displayed on a wall in a museum. The wall has a width of (x + 2) feet and an area of (x^2 + 17x + 30) ft^2. Write expressions for the length and width of both the rug and wall. Then find the dimensions of the rug and the wall if x = 20 feet.

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) = .
