There are 156 rows of trees altogether.
<u>Step-by-step explanation:</u>
Given that for every 11 rows of Red delicious , they plant 3 rows of Royal Gala.
Thus for 1 row of Royal Gala there would be 11/3 rows of Red delicious.
Number of rows of Royal Gala=18
For 11 rows of red delicious,they plant 7 rows of yellow delicious.
Thus for 1 row of Red delicious,there would be 7/11 rows of yellow delicious.
For 66 rows of red delicious there would be
For 11 rows of red delicious,they plant 5 rows of Braeburn
for 1 row of red delicious,they would plant 5/11 rows of Braeburn.
For 11 rows of red delicious,they would plant
Total rows of trees=66+42+30+18=156
The domain of a(x) is all of R. The domain of b is the range where 
. We can calculate the composition boa by changing in the expression for b, every x with a(x). Hence, boa(x)=
=
. Again for a function with a root to be defined, we need that the expression under the square root has to be positive. Hence, 3x-3
0.Thus, the set where this holds is 
. This is also the domain of the function boa(x).
