Answer:
Step-by-step explanation:
The first thing you want to do is to factor in any quadratic equation.
So, -10(x^2-25)
Now, we see this is a special case, whenever we see a equation in this case, x^2 - b^2, we factor it to this (x+b)(x-b)
So, -10(x+5)(x-5)
x = -5 and x = 5

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.
The answer will be fg = 7 and fx = 7
If you divide those two you get <span>0.0024691358 hope that helped</span>
The way I like to do this is divide the numerator(top number) by the denominator(bottom number) So you have one fifth, which is written as 1/5
1 divided by 5 is .2
ANSWER: .2
Hope this helped!!(:
