A large snowplow can clear a parking lot in 5 hours. A small snowplow needs 8 hours to clear the lot. Working together, how long would it take them to clear the
lot?

16.5 I think

Step-by-step explanation:

can you let me know if you are working on finding averages right now? Bc if so the answer I gave is right bc I just did the average of the two.

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
