The Venn diagram is given below. Then the number of students who have brother and sister will be 6.
<h3>What are sets?</h3>
A set is a group of clearly specified components. The number of items in a finite set is denoted by a curly bracket.
In a class of 20 students:
11 have a brother, 9 have a sister, and 6 have neither.
Then the Venn diagram will be
11 – a + a + 9 – a = 20 – 6
20 – a = 14
a = 6
The Venn diagram is given below.

Step-by-step explanation:
hope it is helpful to you
2x + y = 3 is the blue boundary line...the shading is below the line which means 2x + y is less than or equal to 3
y - x = 2 is the red boundary line... the shading is above the line which means
y - x is greater than or equal to 2
ANSWER: 2x + y is less than or equal to 3 and y - x is greater than or equal to 2
Answer:
31.4
Step-by-step explanation:
Because you multiply the circumference by pi
I think it’s the quadratic trinomial because a trinomial has three terms and the problem has the terms.
