Answer:
17
Step-by-step explanation:
The computation of the number of elements are in (A ∩ B) is shown below;
Given that
Set A contains 35 elements
And, set B contains 22 elements
Now if there are 40 elements in (A ∪ B)
So, the number of elements are in (A ∩ B) is
= 35 + 22 - 40
= 17
Answer: The correct line is

Step-by-step explanation: We are given the following two sets of quadratic expressions in various forms:

We are to select one of the lines from above that represent three equivalent expressions.
We can see that there are three different forms of a quadratic expression in each of the lines:
First one is the simplified form, second is the factorised form and third one is the vertex form.
So, to check which line is correct, we need to calculate the factorised form and the vertex form from the simplified form.
We have

and

So,

Thus, Line 1 contains three equivalent expressions.
Now,

and

So,

Thus, Line 2 does not contain three equivalent expressions.
Hence, Line 1 is correct.
