<span> (3x^3 - 7x^2 + 12) - (3x^3 + 6x^2 + 10x)
</span>First, remove parentheses
3x^3 - 7x^2 + 12 - 3x^3 -6x^2 -10x
eliminate the opposites
then collect the like terms
13x^2 +12 - 10x
and finally, use the commutative property to reorder the terms, and you'll get
-13x^2-10x+12
Answer:
50

Answer:
0.7 hours
Step-by-step explanation:
Given that Irina was able to make the same distance from work to home in 0.4 of an hour at 27 miles per hour, we can use this rate and time to find the distance she travels to and from work using the general formula:
d = rt, where d=distance, r = rate and t = time
d = 27(0.4) = 10.8 miles
Since the distance from Irina's home to work is 10.8 miles, we can again use the formula 'd = rt' to find the time it takes her to bike to work at a rate of 16 miles per hour and solving for time, 't':
10.8 = (16)t
t = 0.7 hours
