Multiplying out the equation (3x - 8)(2x^2 + 4x - 9) will get you;
6x^3 + 12x^2 - 27x - 16x^2 - 32x + 72
Combine like terms;
6x^3 - 4x^2 - 59x + 72
So the coefficient for the x^3 is 6.
The coefficient for the x^2 is -4.
The coefficient for the x is -59.
6 / 2/5
6 * 5/2
30/2

The function rule that relates the number of miles traveled to the hours driven is d = 55t
<h3>What is speed?</h3>
Speed is the ratio of distance traveled by a body to the time taken.
The formula for calculating distance is expressed as:
Given that the speed is 55 miles per hour
55 = d/t
Cross multiply
d = 55t
Hence the function rule that relates the number of miles traveled to the hours driven is d = 55t
