Concept explainers
i.
To state: The expression
The resultant value of the expression is 18.
Given information:
The given expression is
Explanation:
Consider the expression
Substitute the value of x as -3 in the given expression,
Simplify powers and multiply,
Simplify terms within brackets and multiply,
Add and subtract from left to right,
Add and subtract from left to right,
Therefore, the value is 18 for x equal to 3.
ii.
To state: The given expression in part (a) is
The resultant answer is 18.
Given information:
The given expression is
Explanation:
Consider the expression
Remove the grouping symbol,
Use Commutative property,
Use Distributive property,
Combine like terms and simplify,
Now evaluate
Substitute the value of x as 3,
iii.
To state: The reason why the values in both parts (a) and (b) should be same.
Because both expressions were equivalent and value of x was same for both the expressions.
Given information:
The given statement says to explain why the values in both parts (a) and (b) should be same.
Explanation:
It can be seen that the resultant values in both parts (a) and (b) are same.
The values of both the parts should be same because the substituted values of x in both the part are same
In part (a), the value of x is substituted directly in the expression
In essence both the expressions were equivalent and the substituted value of x is also same for both the parts.
