with the ground. How high up the wall does the ladder reach? Round your answer to the nearest tenth of a foot if necessary.

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Polynomial that can be factored as (3x-4)(3x+4)

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days
