When you make the product of a binomial of the kind x + a times other binomial that is of the kind x - a, you obtain another binomial (not a trinomial), so any example with that form will be a counterexample that disproves the conjecture:
(x + a) * (x - a) = x^2 - a^2
For example, (x +3) * (x - 3) = x^2 - 9. So, not always the product of two binomials is a trinomial.
Answer:
Rates. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

Answer:
Joey needs to eat 7 hot dogs per minute to break his own record in next 9 minutes.
Step-by-step explanation:
Joey needs more than 72 hot dogs in 10 minutes to break his own record.That means Joey needs to eat at least 73 hot dogs in 10 minutes.
After 1 minute Joey has eaten = 10 hot dogs.
In remaining 9 minutes balance hot dogs = 73-10 =63
Therefore per minute hot dogs to be eaten = 63/9 =7
So answer is 7 hot dogs per minute to be eaten.
