For this case we have the following functions:

We must find
By definition of operations with functions we have:

So:

Answer:
Option A

Standard form: 7z^4-6z^2-6z
This IS a polynomial, it's degree is 4 and has 3 terms
Answer:
The attorney worked for 32.5 hours in order for his total bill to be $3,500.
Step-by-step explanation:
Let's set up an equation with some variables:
= hours of service
= total bill

Plugging in our given values, we get:

And solving for
, the hours the attorney worked, we get:

Answer
given,
352 + 116
we have to break 116 and use it on open number line
breaking of number 116
116 = 100 + 10 + 6
And addition will be shown in the number line attached below
now,
352 + 100 = 452
452 + 10 = 462
462 + 6 = 468
we know
sum of
352 + 116 = 468
Im thinking its 32.6 but im not for sure
