The final expression would be -5x -50.
You could've got this by multiplying -5 and x together, which is -5x.
Multiply -5 and 10 together, and you get -50.
This is also called the Distributive Property. Hope this helped :)
Answer:
Letter B would be your answer because 20 feet ABOVE sea level is positve. 20 feet BELOW sea level is negative because you are decreasing from sea level. Then sea level would be zero because it is at its place , there is no measurment because sea level is flat

Answer:
we have the expression as;
1/sin u cos u
Step-by-step explanation:
tan u = sin u/cos u
cot u = cos u/sin u
Thus;
sin u/cos u + cos u/sin u
The lcm is sin u cos u
Thus, we have that;
(sin^2 u + cos^2 u)/sin u cos u
But ; sin^2 u + cos^2 u = 1
so we have ;
1/sin u cos u
