Answer:
45x^3 + 123x^2 + 104x + 28
=(45x^3 + 60x^2 + 20x) + (63x^2 + 84x + 28)
=5x(9x^2 + 12x + 4) + 7(9x^2 + 12x + 4)
=(5x + 7)(9x^2 + 12x + 4)
=(5x + 7)(3x + 2)^2
=> Option D is correct
Hope this helps!

Answer:
6.74cm
Step-by-step explanation:
Area of circle = π * r * r = 35.6
Radius of circle = √(35.6 ÷ π) ≈ 3.37
Diameter of circle = 2 * r = 6.74cm
- Factor out 7 from the expression and remaining will be
<h3>Hence,Option C is correct..</h3>
In the given question, all the necessary information's are already provided. Using these information's it is easy to find the average speed of the car in miles per hour. It is given that the car covers 10 laps in 18 minutes and each lap is 3.6 miles in length.
Total distance covered by the car = (10 * 3.6) miles
= 36 miles
Now we have to convert the time from minutes to hours. So
18 minutes = 18/60 hours
= 3/10 hours
Now we can easily calculate the average speed of the favorite car of Mathew.
Average Speed = 36 * (10/3) miles/hour
= 120 miles/ hour
