A section of the theater has been reserved for 378 people . If each row in the theater seats 18 people, how many rows have been reserved

21 reserved rows

Step-by-step explanation:

If A section of the theater has been reserved for 378 people and each row seats 18 then

378 divided by 18 = 21 reserved rows

21 rows have been reserved

Step-by-step explanation:

You divide 378 by 18

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.
