It takes you 39 seconds to walk from the first (ground) floor of a building to the third floor. how long will it take you to walk from the first floor to the sixth floor (at the same pace, assuming all floors have the same height)

Use continuity to evaluate the limit. lim x→16 20 + x 20 + x step 1 consider the intervals for which the numerator and the denominator are continuous. the numerator 20 + x is continuous on the interval the denominator 20 + x is continuous and nonzero on the interval

Two lines parallel to the same plane are parallel to eachother

Which value would be a solution for x in the inequality 47-4x< 7
