Answer:
the difference is 14
Step-by-step explanation:
subtracting 3x2 4x – 5 from 7x2 x 9 results in a polynomial
Subtract
Multiply negative inside the parenthesis
Now we subtract 4x^2 -3x from the result
14
Speed: 30mi/sec
Seconds in one minute: 60
Seconds in 6 minute: 60 x 6 = 360 seconds
take the speed of 30miles / seconds and times it with 360, and you get a total distant traveled: 10800 miles
Answer:
7
Step-by-step explanation:
23 is a prime number, therefore there are two possibilities:
or
Now, we check if any of these solutions is also a solution to the second equation:
Therefore, 3 is not a solution.
Therefore, 4 is a solution.
We know that and , therefore there isn't any , for which , so there's no solution.
So, the only solution is .
