Answer:
a^12+8
Step-by-step explanation:
let's check all the expressions
1. a^3+18
here 18 is not a perfect cube.
2. a^6+9
here 9 is not a perfect cube.
3. a^9+16
here 16 is not a perfect cube.
4. a^16+8
here 8 is a perfect cube, thus we can write above expression by using laws of exponents as
(a^4)^3+2^3
Thus, is a sum of cubes.

Answer:
54 degrees
Step-by-step explanation:
If these two lines are parallel, than angles 1 and 7 are supplementary.
13x+9+5x+9=180
18x+18=180
x+1=10
x=9
Angle 6 and 7 are vertical angles, so they are equal. Therefore, angle 6 is:
5x+9=5(9)+9=54
