Answer:
x^2+11x+10
or
(x+1)(x+10) since you can factor x^2+11x+10
Step-by-step explanation:
Let's do synthetic division.
We are dividing by x+2, so -2 will be on the outside. Like this:
-2 | 1 13 32 20
| -2 -22 -20
|___________________________
1 11 10 0
The remainder is 0, so (x+2) is indeed a factor of x^3+13x^2+32x+20.
The other factor we found by doing this is (x^2+11x+10).
You can find more factors by factoring x^2+11x+10.
Two numbers that multiply to be 10 and add to be 11 is 10 and 1 so the factored form of x^2+11x+10 is (x+10)(x+1).
Average speed = Total distance/Total time.
First drive:
120/60=2 (distance/rate=time)
Second drive:
120/40=3 (distance/rate=time)
Average:
Total time=120+120=240
Total time=3+2=5
Average speed = Total distance/Total time=240/5=48
His average speed was 48 mph.
