Answer: B: 35ab^2c AND 7bc^2
Step-by-step explanation:
So at the end of the third year, it would be 800 x^3 + 600x^2? And he doesn't work the third summer? Then 800x^3 + 600x^2 = 1650 x = 1.0657758228... so he needs an interest rate of 6.57758.... % compounded annually.
To find p, you would first subtract the 4 from either side of the equation. You would then have 3p+15. Then you would divide by 3 on both sides to get 9=5.
Therefore, p=5
Area=Length×Width
Width=Area÷Length
So, the answer should be 25/54÷5/9=25/54×9/5=225/270=5/6 mills
Length=5/9 miles
Area=25/54 square miles
Width=5/6 miles
