The answer will be 120y^2
Answer:
9
Step-by-step explanation:
Missing point will be represented by X
(5+8+7+11+X)/5 = 8
Multiply 5 to get rid of and...
5+8+7+11+X = 40
Simplify
31+X = 40
Subtract
X=9
Jaira is completing the construction of a regular hexagon inscribed in a circle, as shown below: The next step in her construction should be:
- construct another pont E by placing her compass at the locus D
- Repeat the process to get 6 more points on the given circle then join all of them together.
<h3>
What is a regular hexagon?</h3>
A closed polygon with six equal sides and six equal angles is called a regular hexagon.
Thus, the steps highlighted above will help Jaira complete her construction.

<h2>Answer</h2>
Coordinates of point B':
B' = (-1, -4)
<h2>Explanation</h2>
To reflect a point or a figure across the x-axis we use the rule:
→
In other words, we multiply the y-coordinate of our points by -1, while leaving the original x-coordinate as it is.
Let's apply the rule to every point of our triangle :
A = (2, 1)
A' = (2, 1*-1) = (2, -1)
B = (-1, 4)
B' = (-1, 4*-1) = (-1, -4)
C = (3, 7)
C' = (3, 7*-1) = (3, -7)
Formulas:
A= (b1+b2) /2 X h
A= (22.2+8.52) x 9.86
A=30.72x9.86
A= 302.90
