A box is shaped like an octagonal prism. What is the area of the base

Step-by-step explanation:

An octagonal prism is a polyhedron consisting of two equal and parallel faces called base. In an octagonal prism its bases are shaped like an octagon. Therefore, the area of the base of this box is basically the area of an octagon.

An octagon is a flat geometric figure consisting of 8 sides and 8 vertexes. The area of a regular octagon of side length is given by:

answer: check all that apply, where the options?

step-by-step explanation:

- "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."
