Is there a picture that goes along with the question?
Answer:
He traveled for 2.5 hrs at 54 mi/hr
He traveled for 3 hrs at 61 mi/hr
------------------------------
check:
(1) +d+=+54t+
(1) +d+=+54%2A2.5+
(1) +d+=+135+ mi
<span>m/5 + 3(m - 1) = 2(m - 3)
m + 15(m - 1) = 10(m - 3)
m + 15m - 15 = 10m - 30
6m = -15
m = -15/6</span>
The option (C) f(x) = (x+2)(x-3)²(x+4) is correct because in the graph the minimum value of function is less than 40.
<h3>What is polynomial?</h3>
Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.
![\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n](https://tex.z-dn.net/?f=%5Crm%20a_1x%2Ba_2x%5E2%2Ba_3x%5E3%2Ba_4x%5E4..........a_nx%5En)
We have a graph of a polynomial.
From the graph we can clearly see there is three x-intercept where the value of a polynomial function becomes zero.
The minimum value of function is less than 40
At x = 3, f(3) = 0
At x = -2, f(-2) = 0
At x = -4, f(-4) = 0
Thu graph of a function will be:
![\rm y\ =\ \left(x+2\right)\left(x-3\right)^{2}\left(x+4\right)](https://tex.z-dn.net/?f=%5Crm%20y%5C%20%3D%5C%20%5Cleft%28x%2B2%5Cright%29%5Cleft%28x-3%5Cright%29%5E%7B2%7D%5Cleft%28x%2B4%5Cright%29)
Thus, the option (C) f(x) = (x+2)(x-3)²(x+4) is correct because in the graph the minimum value of function is less than 40.

Ok, so lets suppose there are 10 people there:
8 are women
2 are men
The average of the total is:
