Answer:
5(3x + 5) or 15x + 25
Step-by-step explanation:
A regular pentagon has 5 sides of equal length. The perimeter is the sum of the lengths of those sides. We can use multiplication to find the sum of 5 of the same value:
P = 5(3x +5)
Perhaps you want it expanded. Using the distributive property, we multiply each term in parentheses by 5:
P = 15x + 25
Experimentally we got a five 9 times out of 50
Answer: 9/50

Given:
In triangle XYZ, x = 27 cm, y = 79 cm and
.
To find:
The length of z.
Solution:
In triangle XYZ, using the Law of cosine, we get

Putting the given values in the above formula, we get




Taking square root on both sides.


Approx the above value to the nearest number and side length cannot be negative. So,

Therefore, the length of z is about 102 cm.
