To attempt this algebraic equation we will be multiplying 4 to (3 - x) bracket so as to form the term on L.H.S.



Combining like terms, we get,





R=12.13
A=pi×r²
A=pi×12.13²
A≈462.2442041
A≈462.2 (to the nearest tenth).
So the answer is A≈462.2.
Answer:
Then, the object will take 29.11 min to travel 
Step-by-step explanation:
When an object is moving at a steady speed, we can calculate the time it would take to travel a given distance using the following formula:
(equation 1)
In this particular, both the given speed and distance are mixed fractions so we'll first convert them into improper fractions to operate more easily:


So, now we can calculate the time using the equation 1:


And, if we want the result in minutes:

Then, the object will take 29.11 min to travel 
It is 8.5, how you get it is simple. (Divide 102 by 24, then add 4.25 to that answer)
