Step-by-step explanation:
Use the distributive formula to solve for n:
-a(b + c) = -ab - ac
So, to solve this you would have to use the distributive property:
-1/3n - 5 = -2
Add 5 to both sides
-1/3n - 5 + 5 = -2 + 5
-1/3n = 3
Now, multiply -3 from both sides
-1/3 * -3 n = 3 * -3
Simplify
n = -9
Hope that helped!!

<span>The distance from the vertex to the centroid is twice the distance from the centroid to the side.
This means that 3x + 5 = 2 * (2x)
</span><span>3x + 5 = 4x
x = 5

This looks like common core which is never straight forward.It seems as though they are asking for the perimeter and not area,since they used feet for the distance around instead of sq.ft.
We would need the fractions given
