Answer:
22.5m
Step-by-step explanation:
450m²÷20m=22.5m
Answer:
k=32
Step-by-step explanation:
Given the points:
The first step is to find the <u>Centroid</u> of the triangle.
Centroid, X
Next, let P be a point (x,y)
Using the <u>distance formula, </u>
<u />
<u />
<u />
On Substitution into: 
![(x-4)^2+(y-(-1))^2+(x-6)^2+(y-2)^2+(x-(-1))^2+(y-2)^2=3[(x-3)^2+(y-1)^2]+k](https://tex.z-dn.net/?f=%28x-4%29%5E2%2B%28y-%28-1%29%29%5E2%2B%28x-6%29%5E2%2B%28y-2%29%5E2%2B%28x-%28-1%29%29%5E2%2B%28y-2%29%5E2%3D3%5B%28x-3%29%5E2%2B%28y-1%29%5E2%5D%2Bk)
Let us simplify the LHS first
Also, the Right Hand Side
![RHS:3[(x-3)^2+(y-1)^2]+k\\=3[x^2-6x+9+y^2-2y+1]+k\\=3x^2-18x+27+3y^2-6y+3+k\\=3x^2+3y^2-18x-6y+30+k](https://tex.z-dn.net/?f=RHS%3A3%5B%28x-3%29%5E2%2B%28y-1%29%5E2%5D%2Bk%5C%5C%3D3%5Bx%5E2-6x%2B9%2By%5E2-2y%2B1%5D%2Bk%5C%5C%3D3x%5E2-18x%2B27%2B3y%5E2-6y%2B3%2Bk%5C%5C%3D3x%5E2%2B3y%5E2-18x-6y%2B30%2Bk)
Therefore:
Answer:
3n^2+n-2
Step-by-step explanation:
Coefficient is the number that we multiply an expression that contains a variable. In all the expressions above the variable is n.
Some examples:
Coefficient of n^2 is 1.
Coefficient of n in n^2+2n+1 is 2.
Solution:
In 5n^2+6n-1 the Coefficient of n is 6.
In 2n^2+5n+1 the Coefficient of n is 5.
In 40^2 - n +9 the Coefficient of n is - 1.
In 3n^2 +n - 2 the Coefficient of n is POSITIVE 1.
We tend to not write 1*n because 1*n=n.
Step-by-step explanation:
Simple the pattern is add 3
So next is 22
