Answer:
A. No solution
Step-by-step explanation:
The given equation is 4(2 x + 9) = 4(2 x +6)
We divide through by 4 to get:
2 x + 9 = 2 x +6
We now group similar terms to obtain:
![2x - 2x = 6 - 9](https://tex.z-dn.net/?f=2x%20-%202x%20%3D%206%20-%209)
![0 = - 3](https://tex.z-dn.net/?f=0%20%3D%20%20-%203)
This final statement is false.
Therefore the given equation has no solution.
Three is also 44 and two and four are 136

The race is 1.2 miles long</h2>
Step-by-step explanation:
The first leg is 3/10 mi, the second leg is 1/2 mi, and the third leg is 2/5 mi.
![\texttt{Length of first leg = }\frac{3}{10}miles\\\\\texttt{Length of second leg = }\frac{1}{2}miles\\\\\texttt{Length of third leg = }\frac{2}{5}miles](https://tex.z-dn.net/?f=%5Ctexttt%7BLength%20of%20first%20leg%20%3D%20%7D%5Cfrac%7B3%7D%7B10%7Dmiles%5C%5C%5C%5C%5Ctexttt%7BLength%20of%20second%20leg%20%3D%20%7D%5Cfrac%7B1%7D%7B2%7Dmiles%5C%5C%5C%5C%5Ctexttt%7BLength%20of%20third%20leg%20%3D%20%7D%5Cfrac%7B2%7D%7B5%7Dmiles)
Now we need to find length of race
![\texttt{Total length = }\frac{3}{10}+\frac{1}{2}+\frac{2}{5}\\\\\texttt{Total length = }\frac{3}{10}+\frac{5}{10}+\frac{4}{10}\\\\\texttt{Total length = }\frac{3+5+4}{10}\\\\\texttt{Total length = }\frac{12}{10}\\\\\texttt{Total length = }1.2miles](https://tex.z-dn.net/?f=%5Ctexttt%7BTotal%20length%20%3D%20%7D%5Cfrac%7B3%7D%7B10%7D%2B%5Cfrac%7B1%7D%7B2%7D%2B%5Cfrac%7B2%7D%7B5%7D%5C%5C%5C%5C%5Ctexttt%7BTotal%20length%20%3D%20%7D%5Cfrac%7B3%7D%7B10%7D%2B%5Cfrac%7B5%7D%7B10%7D%2B%5Cfrac%7B4%7D%7B10%7D%5C%5C%5C%5C%5Ctexttt%7BTotal%20length%20%3D%20%7D%5Cfrac%7B3%2B5%2B4%7D%7B10%7D%5C%5C%5C%5C%5Ctexttt%7BTotal%20length%20%3D%20%7D%5Cfrac%7B12%7D%7B10%7D%5C%5C%5C%5C%5Ctexttt%7BTotal%20length%20%3D%20%7D1.2miles)
The race is 1.2 miles long
