If you mean 9% of 153 your answer is 13.77
When you do (f+g)(x), all you have to do is take both functions and add them to each other. It should look like this when you set it up:

Then just add like terms and you should get:

Hope this helped.
Answer:
See proof below
Step-by-step explanation:
Let
. If w=-z, then r=0 and r is real. Suppose that w≠-z, that is, r≠0.
Remember this useful identity: if x is a complex number then
where
is the conjugate of x.
Now, using the properties of the conjugate (the conjugate of the sum(product) of two numbers is the sum(product) of the conjugates):

=
Thus
. From this,
. A complex number is real if and only if it is equal to its conjugate, therefore r is real.
Answer:
for angle H ,
hypotenuse = gh( √77)
adjacent side= ih( √35)
perpendicular=gi( √42)
then
we know
secant=hypotenuse /adjacent
=√77/√35
