Answer:
1. Write the addition of "a", "b" and "c".
2. The equation is: 
Step-by-step explanation:
You know that <em>P</em> represents the perimeter of the triangle and <em>a, b </em>and <em>c </em>represent the sides of the triangle.
By definition, the sum is the result of an addition. Therefore, the statement "The perimeter <em>P</em> of a triangle is equal to the sum of the lengths of sides <em>a, b</em>, and <em>c</em>”, indicates that the perimeter is obtained by adding the lengths of the sides of the triangle.
Knowing this, you can write the following equation:

3.14(10²) - 3.14(6²)
3.14(10² - 6²)
3.14(100 - 36)
3.14(64)
200.96
201
Answer:
36 and 14
Step-by-step explanation:
Create an equation
x+x-22=50
Combine like terms
2x-22=50
Add 22 on both sides
2x=72
divide 72 by 2
x=36
subtract 22 from 36
14+36=50
Hope this helps! :P
<span> 2ab + 2bc + 2ac the formula for the rectangular prism and i'm guessing you would find the answer to this than you would find your formula for the cube which is </span><span><span>6 a </span>2 and you would find that answer.
</span>You would take your total for the rectangular prism answer and subtract the cube answer from it and you would probably get your answer.
hope that helped?!
