Step-by-step explanation:
f(x)=2x+1
g(x)=2x-7
now,
- f-g(x)=f(x)-g(x)
- 2x+1-2x+7
- 8
(f-g)(x)=8
hope it helps.
I think you worded that a little wrong
A is a 5th degree polynomial.
Answer:
44.1
Step-by-step explanation:
Cosine = Adjacent over Hypotenuse
Adjacent of ∠T = 28 and hypotenuse = 39
Which means that 
Now we solve for x
To get rid of the "cos" we take the inverse of cos ( which is
) and apply it to each side

We're left with x = 44.11461855
Our last step is to round to the nearest tenth and we get that the answer is 44.1
