Vocabulary: is a repeating decimal a rational number? A: Yes, because it can be written in the form a/b, where a & b are integers b≠10

B: Yes, because it can be written in the form a • b, where a & b are integers

yes

Step-by-step explanation:

repeating or recurring decimals are decimal representations of numbers with infinitely repeating digits.

numbers with a repeating pattern of decimals are rational because when you put them into fractional form, both the numerator A and denominator B become non-fractional whole numbers.

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.
