Answer:
Step-by-step explanation:
If x represents Caitlyn's age, then can be used to represent Carl's age, and can be used to represent Daryl's age.
The product of Caitlyn and Daryl's ages is at least 160. Use this information to set up an inequality to represent this situation.
The answer is x squared +9x+14 is greater than or equal to 160.
The inequality that represents the given situation where x is the age of Caitlyn will be (X+2) (x+7) ≥ 160.
The inequality equation is a representation of the relation between two or more expressions that are not equal, not equal to, less than, or greater than.

Solution:
It is given that,
Caitlyn's age = x,
Carl's is two years older than Caitlyn, therefore,
Carl's age = x + 2
And, Daryl is 5 years older than Carl, therefore,
Daryl's age = Carl's age + 5
= (x + 2) + 5
= x + 7
The last condition is that the product of Carl and Daryl's age is at least 160, at least is represented as ≥ which mean that value either equal or greater than.
Therefore, the inequality would be (x+2) (x+7) ≥ 160
