Subtraction Property of Inequality is used to solve the given inequality
<em><u>Solution:</u></em>
Given inequality is:

To solve the inequality, subtract 8 on both sides,
We know that,
Adding or subtracting the same quantity from both sides of an inequality leaves the inequality symbol unchanged
Also, by Subtraction Property of Inequality,
If you minus a number from one side of an inequality, you have to minus that same number from the other side of the inequality as well

Thus, Subtraction Property of Inequality is used
<span>Think about which perfect squares lies on the immediate left of 52 and which lies on the immediate right of 52.
49 ---- 52 ------- 64
After that, take the square roots of each of the three numbers.</span>
