Answer:

2x^3 + 3x^2 - 11x - 6.

Step-by-step explanation:

(2x+1) (x-2) (x+3)

= (2x + 1)[x(x + 3)-2(x + 3)]

= (2x + 1)(x^2 + x - 6)

= 2x(x^2 + x - 6) + 1(x^2 + x - 6)

= 2x^3 + 2x^2 - 12x + x^2 + x - 6

= 2x^3 + 3x^2 - 11x - 6.

Good morning,

Answer:

Step-by-step explanation:

(2x+1) (x-2) (x+3)

= (2x+1) [(x-2) (x+3)]

= (2x+1) [x²+3x-2x-6]

= (2x+1) [x²+x—6]

= 2x³+2x²-12x+x²+x-6

=2x³+3x²-11x-6.

gayaneshka [121]

Some of the rates that can be formed are; Speed = 8.333 mph

Number of miles covered per gallon of gasoline used = 14.706 mpg

The number of gallons used per hour = 0.567 gallons per hour

<h3>How to use units conversion?</h3>

We are told that the Northwest Football team drove 25 miles.

Now, the time that this team took was 3 hours.

Thus, one rate that can be formed is the speed in mi/hr. Thus;

Speed = 25/3 = 8.333 mph

Another rate that can be found is the number of miles covered per gallon of gasoline used. This gives us;

25/1.7 = 14.706 mpg

Another rate that can be gotten is the number of gallons used per hour;

= 1.7/3 = 0.567 gallons per hour

Answer:

The simplest answer is

$\frac{16}{21}$

The reason how I got that is because to divide fractions, you have to turn them improper. Once you've done that, you then can multiply it by using the reciprocal of the second fraction. Once they are rearranged, multiply all the numerators by each other. do the same with the denominators and form a new fraction.
