Step-by-step explanation:
Assuming the given equation is

To solve for r, we first divide both sides by a.

We now subtract 5 from both sides:

We now divide through by - 1 to get:

Or

Answer:
See below
Step-by-step explanation:
Firstly, we'll dilate EFGH by any scale factor.
<u><em>Let's find the scale factor first.</em></u>
=> Scale Factor = 
=> Scale Factor = 
=> Scale Factor = 1.5
1) Dilate the figure by a scale factor of 1.5
2) Reflect it across the origin
3) Translate (Move) 5 units down and then 10 units left.
These transformations will map EFGH onto its image.

Step-by-step explanation:
Your question is incomplete as the diagram of the polygon is not attached.
However, I'll give a general guide to calculate the area of a regular polygon.
If you apply these steps, you'll be able to solve your question.
The area of a regular polygon is calculated this.
Area = ½ap
Where a represents the apothem of the polygon and p represents the perimeter of the polygon.
The term "apothem" means the distance between the centre of the polygon and the base of the polygon.
Take for instance, the attachment below.
The polygon is a regular hexagon (it has 6 sides)
The apothem, a = 8.2 ft
The perimeter, p = The sum of all sides of the hexagon
p = (7.6 + 7.6 + 7.6 + 7.6 + 7.6 + 7.6)ft
p = 45.6 ft
Hence, the area of the polygon
A = ½ap becomes
A = ½ * 8.2 * 45.6
A = ½ * 373.92
A = 186.96ft²
