Option C. 6 square units
Step-by-step explanation:
we know that
Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.
Let
a,b,c be the lengths of the sides of a triangle.
The area is given by:

where
p is half the perimeter

6.48/18 = 0.36
Unit rate is 36 cents
Pack of 18:
11.21/18 = 0.6
Unit rate is 60 cents
Pack of 24:
15.85/24 = 0.66
Unit rate is 66 cents
GC:
14.75/30 = 0.49
Unit rate is 49 cents

Unit rate is 43 cents
Comparing all of this data, it can easily be seen that the Frito-Lay mi Variety Pack is the best deal you can find out of these 6 deals.
Answer:
The measure of an interior angle of a regular 15-gon is 120°.
Step-by-step explanation:
We need to determine the measure of the size of an interior angle of a regular 15-gon having 15 sides.
Thus,
The number of sides n = 15
Hence,
Using the formula to determine the measure of an interior angle of a regular 15-gon is given by
(n - 2) × 180° = n × interior angle
substitute n = 15
(15 - 2) × 180 = 15 × interior angle
13 × 180 = 15 × interior angle
Interior angle = (10 × 180) / 15
= 1800 / 15
= 120°
Therefore, the measure of an interior angle of a regular 15-gon is 120°.
Answer:
78
Step-by-step explanation:
Smallest square: 1
Small Square: 2, Area of 4
Mid Square: 3, Area of 9
Mid White Square: 5, Area of 25
Big Square: 8, Area of 64
1 + 4 + 9 + 64 = 78
Given rational expression is:

Now we can simplify this by factoring as shown below:





Hence final answer is
