Answer:
x=64/31
Step-by-step explanation:
31x-4+120=180
31x+116=180
subtract 116 from both sides
Simplify
Divide both sides of the equation by the same term
get answer x=64/31
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

Answer: 4
Step-by-step explanation:
answer:
39.9
Step-by-step explanation:
54= area of rectangle
28.26= area of the circle
divide circle area by 2
= 14.13
subtract half of circle from rectangle area
54- 14.13
= 39.9
Answer:
10
Step-by-step explanation:
The formula for finding the distance between 2 points (x1, y1) and (x2, y2) is
d = √[(x2 - x1)² + (y2 - y1)²]
Here (x2, y2) = (6, -8) and (x1, y1) = (0, 0)
Plugging them gives us
d = √[(6 - 0)² + (-8 - 0)²]
d = √[(6)² + (-8)²]
d = √[36 + 64]
d = √100
d = 10
