Answer: Pipes
Step-by-step explanation: Pipes transfer water around and veins transfer blood around the body
Answer: 
Step-by-step explanation:
Opposite angles of a cyclic quadrilateral are supplementary, so:
This means that 
The Venn diagram of each situation is a diagrammatic way of representing what the situation stands for
<h3>How to make the Venn diagrams?</h3>
<u>Diagram 1: A ∩ B ∩ C</u>
This means that we shade all intersection points of the sets A, B and C
<u>Diagram 2: (A ∩ B) ∪ C</u>
This means that we shade the intersection points of the sets A and B and the whole of set C
<u>Diagram 3: A ∩ (B ∪ C)</u>
This means that we shade the where the set A intersects with the whole of sets B and C
<u>Diagram 4: (A ∩ B) \ C</u>
This means that we shade the intersection point of the sets A and B without shading any point on set C
<u>Diagram 5: (A\B) ∪ (B\C) ∪ (A\C)</u>
This means that we shade all set A without set B, all set B without set C and all set A without set C. In other words, we shade everything in the set without shading set C

The <em>quadratic</em> equation 3 · x² + 7 · x - 2 = 0 has a <em>positive</em> discriminant. Thus, the expression has two <em>distinct real</em> roots (<em>real</em> and <em>irrational</em> roots).
<h3>How to determine the characteristics of the roots of a quadratic equation by discriminant</h3>
Herein we have a <em>quadratic</em> equation of the form a · x² + b · x + c = 0, whose discriminant is:
d = b² - 4 · a · c (1)
There are three possibilities:
- d < 0 - <em>conjugated complex</em> roots.
- d = 0 - <em>equal real</em> roots (real and rational root).
- d > 0 - <em>different real</em> roots (real and irrational root).
If we know that a = 3, b = 7 and c = - 2, then the discriminant is:
d = 7² - 4 · (3) · (- 2)
d = 49 + 24
d = 73
The <em>quadratic</em> equation 3 · x² + 7 · x - 2 = 0 has a <em>positive</em> discriminant. Thus, the expression has two <em>distinct real</em> roots (<em>real</em> and <em>irrational</em> roots).
