Answer: 2 week and 2 days
Step-by-step explanation:
Given
Melody spent 16 days in South America
A week consists of 7 days
In 2 weeks it is, 14 days
So, 16 days is equivalent to 2 weeks and 2 days
Melody spent 2 weeks and 2 days in South America
(-x-14)^2 = x^2 +14x+14x+196
which turns into x^2+28x+196.
hope this helps
and give thanks
Answer:
The two factors will be
Step-by-step explanation:
We have given the equation ![9-16x^4](https://tex.z-dn.net/?f=9-16x%5E4)
We know the algebraic equation ![a^2-b^2=(a+b)(a-b)](https://tex.z-dn.net/?f=a%5E2-b%5E2%3D%28a%2Bb%29%28a-b%29)
As
can be written as
, as square of 3 is 9 and square of
is ![16x^4](https://tex.z-dn.net/?f=16x%5E4)
So ![9-16x^4=3^2-(4x^2)^=(3+4x^2)(3-4x^2)](https://tex.z-dn.net/?f=9-16x%5E4%3D3%5E2-%284x%5E2%29%5E%3D%283%2B4x%5E2%29%283-4x%5E2%29)
So the two factors will be ![=(3+4x^2)\ and\ (3-4x^2)](https://tex.z-dn.net/?f=%3D%283%2B4x%5E2%29%5C%20and%5C%20%283-4x%5E2%29)
Answer:
the answer will be something like 18
