Answer:
(16 + 9) * 2
Step-by-step explanation:
It asks for an expression so there would be no equal sign. Since it says twice, you would multiply the value got from adding 16 and 9 by 2. Put parentheses to confirm order of operations.

4 times 3 is 12
2 times 6 is 12
The answer would be 11.
I hope that this will help somebody :)
For two lines to be perpendicular, their slopes must be negative reciprocals of one another, mathematically:
m1*m2=-1, in this case our reference line has a slope of -3 so:
-3m=-1 divide both sides by -3
m=-1/-3
m=1/3
So the perpendicular line will have a slope of 1/3
