OLEGan [10]
N and m are numbers 3 units apart

n + 3 = m
n = m - 3

Product:

m(m-3) = 108 (ANSWER)
m^2 - 3m - 108 = 0
(m-12)(m+9)=0

m = 12(greates) and -9(void)

n = m - 3
n = 12 - 3
n = 9


therefore the two numbers are 9 and 12

Dovator [93]

Answer:

The constant term in the polynomial is 140 and it represents the revenue when the price is not increased.

Step-by-step explanation:

To find: What is the constant term in the polynomial expression, and what does it represent?

The given expression is -8x^2 + 54x + 140.

To find the constant term we can simply put x=0 in the given equation where x represents the number of $1 increase in price.

=-8(0)^2 + 54(0) + 140

=140

The constant term is 140 and it represents the revenue when the cost of a hot dog is $2.

Hence, the constant term in the polynomial is 140 and it represents the revenue when the price is not increased.
