Stanley Plumb, Bing Cherry, and Walter Mellon decided to form a recording group - The Three Fruits. Not only do they all have wonderful singing voices, but each also plays either guitar or the banjo. If Stanley and Walter can both play the guitar, then so can Bing. If Bing cannot play the guitar, then Walter can; but if Walter plays the banjo, then Stanley does not. Either Stanley or Bing but not both, can play the guitar. Only one of the three can play both the banjo and guitar. Which one?​

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.
