<h3>
Answer: Choice C</h3>
================================================
Explanation:
If all the exponents are even, then the polynomial function is even.
- Choice A has a mix of even and odd exponents here, so choice A is neither even nor odd. We can rule this out.
- Choice B is the same story as choice A. So we can rule that out as well.
- Choice C has all of its exponents even. Therefore function C is an even function, and it's the final answer.
- Choice D is the same story as choice A. The only difference is the leading coefficient is positive.
Answer:
25
Step-by-step explanation:
You need to reverse the operations given that 60 is equal to (2x+10)
so first you would subtract 10 from 60 that would equal 50. that divide by two to get 25.
I think it’s 5 but don’t get mad if it’s wrong
There are an infinite number of solutions, so I don't plan to list them all.
I'll list two of them, and then describe how to get all of the rest.
You said that <u>2cos(x) - 1 = 0</u>
Add 1 to each side: 2cos(x) = 1
Divide each side by 2: cos(x) = 1/2
The angles whose cosine is 1/2 are 60 degrees, 300 degrees,
and any multiple of 360 degrees added to either of those.

Step-by-step explanation:
The equation for the perimeter is ...
P = 2l +2w
The equation for the area is ...
A = lw
Using these equations with the given perimeter and area, we can write the system of equations ...
