What equation or inequality represents the following scenario?

The product of two consecutive odd integers is less than 76, where [tex] n [/tex] is the first odd integer.

A. [tex] n(n+1) < 76 [/tex]
B. [tex] n(n+1) > 76 [/tex]
C. [tex] n(n+2) < 76 [/tex]
D. [tex] n(n+2) \geq 76 [/tex]

Answer :

To solve the problem of finding the inequality that represents the product of two consecutive odd integers being less than 76, let's break it down step by step:

1. Identify the Consecutive Odd Integers:
- If [tex]\( n \)[/tex] is our first odd integer, then the next consecutive odd integer would be [tex]\( n + 2 \)[/tex].
- For example, if [tex]\( n = 3 \)[/tex], [tex]\( n + 2 = 5 \)[/tex].

2. Write the Expression for the Product:
- The product of these two consecutive odd integers can be expressed as:
[tex]\[
n \times (n + 2)
\][/tex]

3. Set Up the Inequality:
- According to the problem, the product needs to be less than 76. Therefore, we have the inequality:
[tex]\[
n \times (n + 2) < 76
\][/tex]

4. Choose the Correct Option:
- Based on the options provided, the inequality is [tex]\( n(n + 2) < 76 \)[/tex]. This matches the requirements of the scenario described.

Thus, the correct inequality that represents this scenario is:
[tex]\[
n(n + 2) < 76
\][/tex]

This inequality captures the relationship described, where the product of two consecutive odd integers is less than 76.
