Answer:
-13
Step-by-step explanation:
f(x)=2x-5 for f(-4)
Let x=-4
f(-4) = 2(-4) -5
= -8 -5
=-13
Answer:
x=5

Answer:
I dont get this ??
Step-by-step explanation:
15.8% would round to 16%
If the number after the decimal point is 5 or greater you round the 5 up to a 6. If it had been less than a 5 it would have rounded down to 15%.
By using x-method we got that factorization
is (x+5)(x-5)
<h3>What is factorization ?</h3>
factorization is writing a expression as a product of several factors.
So Given polynomial is
![x^2-25](https://tex.z-dn.net/?f=x%5E2-25)
Now we will factorise this using x method
Here a=1 b=0 and c= -25
so ac=-25
Now We will write -25 at the top.
and 0 at the bottom.
No we will find two numbers that multiply to the top number -25 and add to the bottom number 0. Hence those numbers are -5 and 5.
Now we can write equation as
![x^2-5x+5x-25\\\\x(x-5)+5(x-5)\\\\(x+5)(x-5)](https://tex.z-dn.net/?f=x%5E2-5x%2B5x-25%5C%5C%5C%5Cx%28x-5%29%2B5%28x-5%29%5C%5C%5C%5C%28x%2B5%29%28x-5%29)
By using x-method we got that factorization
is (x+5)(x-5)
