Unfortunately, you haven't shared the equations from which you're supposed to choose your answer.
But we can write our own.
When will the distance traveled by the 1st car = the distance traveled by the 2nd car?
55 miles + (55 mph)x = (60 mph)x
solve this for x: 55 miles = (60-55)x mph = 5 mph
x=11 hours
The two cars are the same distance from the starting point after 11 hours.
Answer:
x=2
Step-by-step explanation:
Again, trial and error.
Answer:
3 a²b
Step-by-step explanation:
This is what I did:
3 a²b ( 5b² - 7a²)
when you try to expand this, it will give you back the original expansion so 3a²b is the greatest common factor
Answer:
20

<span>Part 1:Is it possible for a composite number to have more than one prime factorization?
Answer: No.
</span><span>Is it possible for a number to have no prime factors? Why?
Answer: Yes. The number 1 has no prime factors, and 1 is not prime.
</span><span>Part 2: Give an example of how prime factorization could be used in the real world.
Answer: A carpenter needs to add two lengths to cut a piece of wood. One length is 5 1/16 inch, and the other length is 3 3/10 in. By using prime factors of 16 and 10, he can find the least common denominator of 16 and 10, and he can add the lengths together.
