Answer to Problem 24STP
The Perimeter of the Triangle is
Explanation of Solution
Given:
The sides of the Triangle are:
Concept Used:
To add two or more monomials that are like terms, add the coefficients; keep the variables and exponents on the variables the same.
To subtract two or more monomials that are like terms, subtract the coefficients; keep the variables and exponents on the variables the same. on the variables the same.
Addition of Algebraic expression
In addition of algebraic expressions while adding algebraic expressions we collect the like terms and add them. The sum of several like terms is the like term whose coefficient is the sum of the coefficients of these like terms.
Example:
1. Add: 6a + 8b, 2b - 4a
Solution:
(6a + 8b) + (2b - 4a) = 6a + 8b + 2b - 4a
Arrange the like terms together, then add. Thus, the required addition
= 6a - 4a + 8b + 2b = 2a + 10b
Calculation:
To add two or more monomials that are like terms, add the coefficients; keep the variables and exponents on the variables the same.
Perimeter of the figure is the sum of all sides.
The sides of the Triangle are:
Add the like terms and the numbers separately.
Thus, the Perimeter of the Triangle is
