Answer:
C. x + 6
Step-by-step explanation:
Start by factoring completely the numerator and the denominator.
2x + 12 = 2(x + 6)
x^2 + 7x + 6 = (x + 1)(x + 6)
The only common factor is x + 6, so the GCF is x + 6
I assume you mean squared? 16r^6^2 YOUR FINAL ANSWER= 16r^256
I do not have an answer but you could always take an explanations how to do it easier. Hope it helps :)
Step-by-step explanation:
Example: solve √(2x+9) − 5 = 0
isolate the square root:
√(2x+9) = 5
square both sides:
2x+9 = 25
Now it should be easier to solve!
Move 9 to right:
2x = 25 − 9 = 16
Divide by 2:
x = 16/2 = 8
Answer:
x = 8
Check: √(2·8+9) − 5 = √(25) − 5 = 5 − 5 = 0
She drives at a rate of 75 miles per hour for three hours, so the first thing you'd do is 75 x 3.
75 x 3= 225
So, she traveled 225 miles to the airport.
Then, she travels at a rate of 400 miles per hour for 4 hours.
4 x 400 = 1,600
That's 1600 miles she traveled from the airport to her destination.
Now to find the total number of miles traveled, add 1,600 and 225.
Total distance traveled: 1825 miles.
