To find the perimeter<span> of a polygon, take the sum of the length of each side. The formula for </span>perimeter<span> of a triangle would be the sum of the three side lengths (a +b+c). In the case, where it is a regular polygon, the perimeter would be 3 times the side length. Hope this answers the question.</span>
Answer:
10 square units
Step-by-step explanation:
We want to find the area under the curve 
from x=1 to x=3.
We use definite integrals to find this area.
We integrate to obtain:
We evaluate the limits to get:
Therefore the area under the curve from x=1 to x=3 is 10 square unit.
256x24 is 6,144, so the manager ordered a total of 6,144 football cards.
The speed upstream is the difference between the boat speed and the current speed. It is (12 mi)/(4 h) = 3 mph.
The speed downstream is the sum of the boat speed and the current speed. It is (32 mph)/(4 h) = 8 mph.
The speed of the boat is the average of these: (3 + 8)/2 = 5.5 mph.
The speed of the current is that less the difference: 5.5 - 3 = 2.5 mph.
_____
<u>Check</u>
Boat + Current = 5.5 + 2.5 = 8 mph
Boat - Current = 5.5 - 2.5 = 3 mph
Hello There!
6x + 7 = ?
x = 12
6(12) = 72
72 + 7 = 79.
There are 79 eggs in total.
Hope This Helps You!
Good Luck :)
