(a)
The value of x
(a)
Answer to Problem 28IP
The solution of the equation is
Explanation of Solution
Given:
The square
Concept Used:
- All sides of square are equal
Rules of Addition/ Subtraction:
- Two numbers with similar sign always get added and the resulting number will carry the similar sign.
- Two numbers with opposite signs always get subtracted and the resulting number will carry the sign of larger number.
Rules of Multiplication/ Division:
- The product/quotient of two similar sign numbers is always positive.
- The product/quotient of two numbers with opposite signs is always negative.
Calculation:
In order to find the value of x, in square all sides are equal so we equate the both sides as below:
In order to find the solution of the equation
Thus, the solution of the equation is
(b)
The length of each sides of the square
(b)
Answer to Problem 28IP
The length of each side of square is
Explanation of Solution
Given:
The solution of the equation is
Concept Used:
- To get rid of a number in addition from one side, subtract the same number from both sides of equal sign.
- To get rid of a number in subtraction from one side, add the same number both sides of equal sign.
- To get rid of a number in multiplication from one side, divide the same number from both sides of equal sign.
- To get rid of a number in division from one side, multiply the same number both sides of equal sign.
Rules of Addition/ Subtraction:
- Two numbers with similar sign always get added and the resulting number will carry the similar sign.
- Two numbers with opposite signs always get subtracted and the resulting number will carry the sign of larger number.
Rules of Multiplication/ Division:
- The product/quotient of two similar sign numbers is always positive.
- The product/quotient of two numbers with opposite signs is always negative.
Calculation:
In order to find the sides of square we put the value of x in both sides as below:
Thus, the length of each side of square is
