C. Step-by-step explanation:

Given:

The expression is given as: The values of 'x' are: Now, plug in 7 and for 'x' in the above expression and determine the value of the expression.

When , the expression is:  Now, let us check the value of each of the options and check which expression is equivalent to the given expression.

Option A: Plug in 5 for 'x' and simplify. This gives, So, this expression is not equivalent to the given expression.

Option B: Plug in 5 for 'x' and simplify. This gives, So, this expression is not equivalent to the given expression.

Option C: Plug in 5 for 'x' and simplify. This gives, Now, plug in 7 for 'x' and simplify. This gives, So, this expression is equivalent to the given expression.

Option D: Plug in 5 for 'x' and simplify. This gives, So, this expression is not equivalent to the given expression.

Option E: Plug in 5 for 'x' and simplify. This gives, So, this expression is not equivalent to the given expression.

Therefore, option C is the correct answer.  ### Other questions on the subject: Mathematics Mathematics, 21.06.2019, christeinberg1 Mathematics, 21.06.2019, logan541972
