What is 28.6 - 0.975 and I need an explanation.

27.625

Step-by-step explanation:

28.600

-0.975

27.625

in words... 28.6-0.975. take away 1 from the 6 and make it five, carry it over to the zero in the hundredths place. Make that 10 a 9 and carry it over to the thousandths place and do 10-5 so in the answer, the thousandths place is 5. 9-7 in the hundredths place is 2 so your answer so far is __._25. take 1 away from 8 and that is now 7 so 15-9 is 6. So your answer so far is __.625. 27-0 is 27 so your answer is 27.625.

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.
