Elaborate 5 contextualized questions about factoring, which can be (Common factor in evidence) (Factoring by grouping, the difference between two squares, a perfect square trinomial) (Factoring the Stevin product, the sum cube and the difference cube of two terms, the sum of two cubes, the difference of two cubes). for those who don't know: contextualized issues that address a specific theme of a real, everyday situation. Ex: Brazil stayed today, due to the last medal disputed in the Olympics in 9th place in the general classification.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."

6e14 is the answer.
