Answer:
k = 8
Step-by-step explanation:
-7k - 9 = 8k - 129
-7k - 8k = -129 + 9
-15k = -120
k = -120/-15
k = 8
Steps to solve:
m + 55 + 1 = m
~Simplify
m + 56 = m
~Subtract m to both sides
56 = 0
No solution

The total area of the figure is 139.20 square centimeters
Areas
The area of a shape is the amount of space it occupies
<h3>Composite figure</h3>
The figure (see attachment) is a composite figure, and the total area is the sum of the areas of each shape that makes up the complete figure
The shape has 6 equilateral triangles, each of which has an area of:

Where:
--- the length of each toothpick
The area of the rectangle is then represented as:


So, the total area of the figure is:

This gives

Substitute 6 for s




Hence, the total area of the figure is 139.20 square centimeters
