For the given set D; the number of elements in the set D as denoted by n(D) is; 4.

Elements of a set.

According to the question;

  • We are required to determine n(D)

The number of elements in a set is given by the notation n(D).

On this note, the set given in this question;

  • D = (4,6,8,10) has 4 elements.

Ultimately, n(D) = 4 elements.

Read more on number of elements in a set;

n(D) = 4

Step-by-step explanation:

Given Data:

Set D = {4, 6, 8, 10}

The number of elements in a set is called the cardinal elements (or) cardinality of the sets. This is denoted by n(A).

Here it is denoted by n(D).

The number of elements in the set D is 4.

The cardinality of the set is 4.

Hence, n(D) = 4.

If the difference of two numbers is 7 and their product is 60, what are they?


X - y = 7.....x = y + 7
x * y = 60

y(y + 7) = 60
y^2 + 7y = 60
y^2 + 7y - 60 = 0
(y + 12)(y - 5) = 0

y + 12 = 0
y = -12....not this one because it is negative

y - 5 = 0
y = 5
