Juliana wants to write the number twenty thousand, one hundred ninety in expanded notation. which the following would complete the expression? select all that apply.
(2x? )+(1x100)+(9x10)
a. 1,000
b. 10^4
c. 100,000
d. 10^3
e. 10,000

B

Step-by-step explanation:

twenty thousand is 20,000

10^4 is 10,000

2x10,000 = 20,000

answer: idk

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.
