Answer:
Complete the square on x by adding <u>49</u> to both sides.
Complete the square on y by adding <u>81</u> to both sides.
Step-by-step explanation:
We have been given an equation
. We are asked to complete the squares for both x and y.
We know to complete a square, we add the half the square of coefficient of x or y term.
Upon looking at our given equation, we can see that coefficient of x is 14 and coefficient of y is 18.
![(\frac{14}{2})^2=7^2=49](https://tex.z-dn.net/?f=%28%5Cfrac%7B14%7D%7B2%7D%29%5E2%3D7%5E2%3D49)
![(\frac{18}{2})^2=9^2=81](https://tex.z-dn.net/?f=%28%5Cfrac%7B18%7D%7B2%7D%29%5E2%3D9%5E2%3D81)
Now, we will add 49 to complete the x term square and 81 to complete y term square on both sides of our given equation as:
![(x^2+14x+49)+(y^2+18y+81)=5+49+81](https://tex.z-dn.net/?f=%28x%5E2%2B14x%2B49%29%2B%28y%5E2%2B18y%2B81%29%3D5%2B49%2B81)
Applying the perfect square formula
, we will get:
![(x+7)^2+(y+9)^2=135](https://tex.z-dn.net/?f=%28x%2B7%29%5E2%2B%28y%2B9%29%5E2%3D135)
Therefore, We can complete the square on x by adding <u>49</u> to both sides and the square on y by adding <u>81</u> to both sides.
Answer:
I really dont know
Step-by-step explanation:
Solution:
1) Add 80 to both sides
-np<60+80
2) Simplify 60+80 to 140
-np<140
3) Divide both sides by p
-n<\frac{140}{p}
4) Multiply both sides by -1
n>-\frac{140}{p}
Done!
