Answer:
<h2>2,268 square units</h2>Step-by-step explanation:
Step 1
Find the area of 1 Triangle
To find this, we will use this formula:
Let's use the formula!
<em>The area of 1 triangle is 189 square units</em>
<em></em>
Step 2
Find the area of the whole intire shape by multiplying the area of 1 triangle with the amount of sides.
There are 12 sides, so let's multiply 189 by 12
189x12=2268
<h2>Hence, the area of the regular polygon is 2,268 square units</h2>
Answer:
9 sides
Step-by-step explanation:
exterior angle + interior angle = 180° , so
exterior angle + 140° = 180° ( subtract 140° from both sides )
exterior angle = 40°
The sum of the exterior angles of a polygon = 360°
Dividing sum by the measure of 1 exterior angles gives number of sides
number of sides = = 9
For the first part:
Every shirt she grabs, will cost her dollars, so if she grabs 3 shirts, then the cost of the shirts is:
With the same rationale, if she grabs 2 pairs of jeans, the cost of the jeans is:
So, her total is:
If you subtract 3 from the total, then the expression is:
For the second part:
If she's paying 3 less for each shirt, then the cost of 3 shirts will become:
In the same fashion, for the two jeans:
So the expression for the total cost is:
For number three:
The amounts are different because the cost of the total purchase is different than the cost of each element that makes up the total purchase.
For number four:
If you're the owner, you want to give the smallest amount of discount (the one in part 1/a).
So you could clarify by saying there's 3 dollars of the TOTAL purchase's cost.
