Answer:
Types of polygon
Polygons can be regular or irregular. If the angles are all equal and all the sides are equal length it is a regular polygon.
Regular and irregular polygons
Interior angles of polygons
To find the sum of interior angles in a polygon divide the polygon into triangles.
Irregular pentagons
The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°.
Example
Calculate the sum of interior angles in a pentagon.
A pentagon contains 3 triangles. The sum of the interior angles is:
180 * 3 = 540
The number of triangles in each polygon is two less than the number of sides.
The formula for calculating the sum of interior angles is:
(n - 2) * 180 (where n is the number of sides)
G(x)= x-1

Answer: 940
Explanation: A quick way to think of this is moving the decimal in 9.4 to the right by two decimal places (since there are two zeroes in 100) Hope this helps! :)

Step-by-step explanation:
Your question isn't complete. But let's assume that the amount earned on Monday is $38 while $25 was earned on Tuesday.
The total amount earned for both days will be:
= $38 + $25
= $63
Since lucky bamboo plants are $7 each, we then divide the total amount gotten by $7. This will be:
= $63 / $7
= 9
Therefore, he can buy 9 lucky bamboos
