Question #3 6th Grade EOG Question #23
Write an expression to represent each
of the following:

A. 17 less than twice a number x

B. the difference between 17 and twice a number x

C. a number x squared, subtracted from 17

D. 17 less than a number x squared

List the sides of δrst in in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12°

Need 50 will mark brainliest answer. find the lengths of all the sides and the measures of the angles.

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) = .
