Suppose set a has 4 elements .what is the least number of elements a subset of a. can have

1 element

Step-by-step explanation:

Call B a set of n elements.

We can say that B is a subset of A if each element of B is also in A. This is written as:

B ⊆A

If a Set B contains all the elements of A, we can also say that B is a subset of A, where B = A.

Therefore, if set A has four elements, then for B to be a subset of A, the number of elements in B must be less than or equal to 4 but greater than 0. {1, 2, 3, 4}

Finally, according to the definition, B must have at least 1 element of A

look up a corrdinate plane and do what the thingy says and boom

-14

step-by-step explanation:

2x2 – 2(x+4)

=2x2-2（5+4）

=4-2×9

=4-18

=-14
